Very nice! The only thing more impressive than all the engineering you’ve done to sound deaden the generator is the fact that you’re a considerate neighbor! Great work sir!
We just survived 4 days of no power in Tulsa, Ok. Our super loud generator almost drove us crazy and I'm surprised one of my neighbors didn't use it for target practice. Your shed is awesome and I plan on using your brilliant design to build my own. I especially like the pneumatic tire idea. Thanks for sharing.
Make sure you view the follow-up videos (linked in the description) for more info on how I built the shed, parts lists, frequently asked questions, etc. Also keep in mind that this was simply how I built my shed, and is intended to give others ideas on things to try. I am not a generator shed expert, although I am an engineer (in another field). So, take my examples with a grain of salt and good luck on your build.
Or just buy an inverter generator, and it will be nice and quiet, reliable, they provide cleaner energy, and use less fuel. I do none of this and its very quiet.
I definitely wanted to buy an inverter generator, but nobody was building one that was powerful enough for my minimum requirements. Honda and Yamaha did not have enough power, and they were 4 times as expensive. After I made the shed, Harbor Freight came out with a Predator 9500 inverter that just barely has enough power. Still haven't seen a lot of inverter generators on the market that have enough power and support 240v, and definitely none that have dual fuel options.
They are expensive, for only twice the price Yamaha does make a cable for "twinning" two generators. This doubles their output, and what we got for our two. Means both generators are also small enough that you can pick them up and put them in the bed of the truck no problem, and yet still have decent output to run must-have items in the home during an emergency. Worked for about a week straight during the Houston flood when we lost power for 6 days. @@C5Tor
@@C5Tor When I decided to get a generator, the first thing on my list was NO GASOLINE. At the time that took out every inverter model on the market, it probably still does.
It’s about time the RUclips algorithm showed a generator shed enclosure with sound deadening material in my results. I’ve been researching (in RUclips lol) and this is the most complete video. Finally getting ready to build and take my garage space back. Thanks for sharing. Just wish the shed prices were cheaper. Can’t find this size shed for anything less than $469. Even from other individuals the cheapest I’ve seen is $400.
Good luck with your build. There are several more videos in this series. I cover how I built the original trashcan muffler in the Exhaust Version 1.0 video (view it here: ruclips.net/video/jZpRSenXJAs/видео.html). Then I did a later video on my Version 2.0 exhaust, which has quite a few improvements over the version 1.0 setup. The newer video has parts lists, shed costs, and other Frequently Asked Questions. Check it out here: ruclips.net/video/y3pUw408jCU/видео.html
That is HANDS DOWN, absolutely the BEST, gas/propane generator sound deadening shed build/review video that I've EVER seen on YT! I'm TOTALLY going to build one just like that! I'm currently using my chicken tractor to house my generator if/when we loose power and have to run the generator and it reduces the noise level at least 50%, but no where near as much as this shed does. I love the ingenuity of using the generator itself to run the fan that cools the shed! Absolute genius brother! Great video and I look forward to watching the build videos now. You've definitely earned my SUB with this video! Thanks
Thanks for the enthusiastic feedback! Stay tuned for some more videos as I upgrade some of the components of the exhaust from 1" to 2" to make the generator breathe a bit easier. I am a bit curious what a chicken tractor is, though. (Nevermind, I looked it up. But I was totally picturing a chicken driving a John Deere.)
I built same 5 years ago. But used two electric fans. Bigger exhaust pipe same shed but From Lowe's. Took truck plastic gas tank mount on back 25 gallon. With gas gauge use almost same cord from Walmart I also put extension on oil. Fill and drain from outside of generator house I used fire proof rock board inside for inside the walls . And key start on outside of generator house installed lights inside for nite time use light switch fuel gauge start and choke mounted on outside generator house. Hook up my own manual transfer switch next main power box easy on and off whole house power. This has been working just over 5 years with many power outages this guy did great job 🤔 but exhaust pipe to small can lead to engine over heating and burnt valve I also used vent covers from ac filter there big and provide lots of air. Key start and light switches , fuel gauge mounted inside water proof case normally was used to cover two outside wall sockets got the biggest one clear door on front when door is open lights come onthere can see fuel gauge and others that mounted in there.used switch for lights from car door interior lights
Sounds like a great setup with lots of convenient customizations for running long term. I wasn't quite that ambitious, as backup power is kind of the secondary function of this generator. I do agree on the exhaust pipe issue on my build. I'm working on version 2.0 of the exhaust setup today. I'm going directly to a 2" pipe to the muffler, and the new muffler has a lot more flow to it (a funky 4" x 8" spiral chamber in the muffler.) Doing some testing this weekend to see how it works. Crossing fingers! Thanks for all the tips!
@@C5Tor thank you. .my exhaust I ran straight out motor to outside with muffler at the end but used stock motorcycle muffler . Love trash can idea . Did you use fiberglass insulation in can I think empty can would make it louder. I also header wrap from advance auto to wrap pipe . Generator bought from harbor freight they must had a return because generator head was changed should have been 10 000watts but came home with 25 000. Watt. For $800. But loves gas my power out after hurricane 2 weeks ran generator whole time 24 7. But off for oil changes. 170 gallons of gas but also had ac on water heater lights had whole house power. .but I love what you did bring back lot of memories. .god bless 😊
Sounds like you got a great deal on that generator! I have another video on how I built the trashcan muffler. I'm actually working on a second video on my Gen II muffler with bigger pipe and better flow. Gen I was super effective at cutting down the sound, but probably had too much backpressure. Might have the new video out next week after some testing. Gen II muffler takes a different approach than the Gen I. Check out the Gen I video here: ruclips.net/video/jZpRSenXJAs/видео.html
This is a very impressive build. Good Job. Another way to keep neighbor's happy is to share some electricity with them. ...A while back a storm took out power in our neighborhood for several days, resulting in the need to run a generator several hours a day to keep freezers and refrigerators cool. I ran a mess of extension cords powering 6 refrigerators and freezers for two neighbors directly, and allowed others neighbors to store food items in fridge/freezers as well as plug in small electronics and coffee makers. This storm ended up being quite a good community building experience and all the neighbors were very grateful and very happy to have light, power and or coffee in the morning. One more tip I wish to share with like minded individuals is that when running things on a generator, it is good to know the load involved. A TV uses (80W), a laptop (50W), a cell phone charger (15W), a cable modem (30W), A typical box fan (80W), and old fashioned light bulb (100W), an LED bulb, (10W), a coffee maker (900W), a microwave (1200W), refrigerator (200-300W), a chest freezer (200W), Window air conditioner (500-1400W), and an Electric space heater (1500W). You do not need to remember all these values as they are legally printed on back of the device by the plug, but having a good solid understanding of what loads what devices are producing helps ensure you don't overload extension cords or the generator.
I Just finished putting together my set up. I would like to thank you for your post and some great tips. Looking forward to ERCOT dropping the ball again this winter. 👍😜

I’m in the process of putting together the same type generator shed. Your homemade muffler idea is next level ! Thanks for the inspiration - looking forward to your next video with more details. Thanks!
Thanks. To clarify: sound will certainly go around corners. (Ask any mom who can hear her kid getting into trouble in the next room!) But that is mostly because the sound gets reflected from some surface. Hard, flat surfaces will reflect it the most. In my application, I tried to make sure that the reflective surface absorbed some of the sound and reflected as little as possible, so the sound had no direct (straight) route out of the box. Thus the "sound doesn't like to turn corners" rule was just my summation of the theory. Not sure if it is written down in any physics books in quite that way.
Thank you !! I will definitely be putting a set of "off road" wheels on my generator. The thing is a beast to move around. Many great ideas with the shed too. Generator thieves are a huge problem when there are long term power outages. Keeping things quiet makes you less of a target.
nice work! huge difference. A lot of people don't understand that the DB measurement is logarithmic, though the numbers don't appear to be that different it is actually a massive reduction with your work!! the fact that we can hear you perfectly clear while you are right next to the genny is awesome!!! now do a shop vac lol
the only drawback to this beautiful design is the distant the current has to travel and it will lose some of it's current because of this variable but --- hey -- so what -- it's quiet - and this to me - he accomplished 100% ... congrats .. I believe I will do the same thing on my gen ... TY :)
Totally agree. The location that I had to put the generator was not ideal. Unfortunately, there wasn't a good place to put it on the other side of my garage, where my electrical box was. So I just got the thickest cables I could get and went from there.
Pretty cool setup. The only recommendation I would have is to remove the propane tank from enclosure . As the tank heats up it builds pressure. If the pressure reaches its limit the tank has a blow off valve. If it blows off inside that enclosure you will turn that enclosure into a large expl*sion.
I've just completed a shed based on your design, after having all the pieces lying around for well over a year. I still have some fine tuning to do and I'm thinking I may add a second fan on the intake side, but WOW is it ever effective. I don't think there is any premade enclosure on the market that could do as well. My Champion 100416 went from 90 dB+ at 10 feet to 70 dB and that is without side baffles. Just leaning a Rockwool panel in front of the intake drops it to 68 dB. One mod I did is replace the stock gas struts with ARANA struts rated at 60 lbs ($22 from Amazon). This is a great upgrade; not only does the lid stay up under the weight of all that Killmat, but you can place it at a good angle to reflect rain or open all the way to vertical. Thank you so much for all of the time and effort you put into sharing your approach with the world. Salute!
Sounds like a great build. I wish I had upgraded the gas struts as well, as the stock ones barely hold up the lid with the added weight. Thanks for sharing!
Good job. I especially liked the vent baffles which is an area most other generator sheds fail to address. Also, great job on the muffler. You can't beat volume for attenuation and you have plenty.
This is awesome. I love the way the generator is protected from the elements and at the same time the noise levels are low enough to not be a nuisance. Great job with this build sir.

Honestly, I didn't watch the video or read many comments, but I'll just tell you that I saw the LPG tank and reg inside the box and it jumped out as something I wouldn't have done. Codes require clearances around natural gas regs (pre-meter) to things like windows, vents into buildings and air inlets to appliances. If the diaphram in the reg has a sudden major failure (rare , but it can happen) , you want that leaking gas to go outside and away from any potential ignition sources. Plus the tank just takes up room and doesn't make any noise anyway. I know bbq's have the tank/reg right next to the flame, but it's still something that most people don't think is an issue until they have what could be a very serious problem. At least that reg you have on your tank is a 2 stage.
Legitimate points. The shed is setup so that you can easily move the propane tank outside of the shed and run the hose back through the blast-gate on the left, along with the electrical cables. And yes, BBQs have the propane tank literally inches from the open flame as well. Leaking propane is never a good thing. I discuss these issues in my later videos on the exhaust and shed.
That’s an awesome set up. You should think about maybe selling the box as a kit to people who want a quiet generator enclosure. I bet it would sell great!
Good idea using the trash can. For permanent stationary engines I have seen people use 55 gallon drums sunk level with the ground full of rock with the exhaust pipe 3/4 of the way down and they are almost dead silent.
The BEST sound/fireproofing solution system in a plastic horizontal shed that I have seen! I intend to build a similar setup for a smaller generator and had planned to make my own 'comfort board' type insulation out of fiberglass batts and 1/2" hardware cloth fencing. This is a huge improvement over what I wa going to try My only concern is that by extending the exhaust as far as you did you may damage the valves on the engine from increased backpressure and heat.
There are several more videos in this series. I cover how I built the trashcan muffler in the Exhaust Version 1.0 video (view it here: ruclips.net/video/jZpRSenXJAs/видео.html).

Not a bad little shed. Sound does actually have no problems with corners. It uses diffraction and reflection through a narrow aperture or across an edge Just make the edges and passage ways aren't that narrow.
I went through this with my camper. my final solution was a 7k Honda in a box. The inverter allows the engine to run much slower. All of his work seems successful, good job. The Honda is portable, but over $3500.
Cool dude. I just bought the exact same generator from Amazon. I plan on trying to set it up with Propane and a switching breaker box and see if I can get it to work like a "stand-by generator" to turn on and off automatically. Using the propane (for convenience ) I won't have to worry about carb clogging and fuel degeneration.
Always nice to have neighbors who are courteous when it comes to sound levels... I do not have such neighbors. Their kids alone would drown out the sound of many generators running in the open. Then the constant leaf, grass blowing and pressure washer... This is an extremely nice setup, and I will definitely be doing the same
I only use my generator during outages so I just have a wooden shed to store it in but no sound proofing. I also have a battery trickle charger to keep the generator battery topped off, the last thing I want is to mess with a pull string during an outage, here it is usually a snow storm or wind storm like last week in Seattle area we had about half a day without power so I kicked off the generator but would be pissed if the battery was dead. Nothing like Propane, no more expired gasoline or blocked carbs just make sure you have enough propane. I have a 500lb tank since I use propane for heating as well so I have the generator hooked up.
Great job with the sound deadening! One thing I would like to point out is I would move the propane cylinder outside for safety, preferably to the yard maybe by running some hardline.
I discuss this in a later video about my 2.0 exhaust setup. Check out my channel for more vids on this subject. The shed is designed so that I can put the propane outside and pass the hose back in via the blast gate.
Great use of a cheap blast gate! This is the best design I've seen so far on RUclips. I have been kicking around the idea of building one for about five years now. I just haven't done it. There were too many unknowns about how well my design would work. I even purchased a metal bicycle/ lawnmower storage box to use for the shell. I had planned to use 1 1/2" fiberglass duct board, but I think rockwool is even more sound-dampening or absorbing, whichever is the right term. I am really impressed with the galvanized garbage can turned into a muffing chamber. Oh, and also the fan outlet box. Did you put a couple baffles in it to route the sound in a few different directions before it exits? Again, Great Work, Sir!
Wow ! You did a superb job on your generator sound suppression box. I don't think I've seen a better designed one anywhere. Are you an engineer ? Big thumbs up.
I did pretty much exactly the same without the muffler. I also added a solar battery tender to keep battery topped up and a solar charged LED strip to bottom of lid in case I need to be starting it up in the dark.
I discuss this very question in a later video on my Version 2.0 exhaust. The LED strip is a good idea. The video also has parts list, shed costs, and other Frequently Asked Questions. Check it out. ruclips.net/video/y3pUw408jCU/видео.html
Great design! Since the actual shed walls are plastic, what if you drilled some small holes in each section and filled them will some type of thick fluid mixture to help beef up the walls? Could you use concrete maybe?
Congrats on a very well thought out design and build! I am in the design process now and will definitely be utilizing a number of your insights! Which Suncast model did you use? I think it's the 70 cubic foot model but I can't be sure. Thanks!!
Yes, I believe it is the 70 cu. ft. model. I bought it "used" off of craigslist. The original owner had purchased it but never put it together, so it was still in the box.
Great job. This is the route that we’re going to have to take since we live in an HOA neighborhood. Have you run the generator loaded to the house? Also, have you done any testing to determine how long your propane tank will last?
We tested the generator interlock when I had it installed. Ran a moderate amount of household items. But the generator won't be big enough to run things like my air conditioner or oven. Microwave is fine. It should keep my fridge cold and the internet running. Don't really know how long a tank of propane will last yet. Still in the testing phase. Specs say the generator can last up to 17 hours on the 6.6 gallon gasoline tank, and about 11 hours on a full 20 lb. propane tank, depending on load, of course. Take that with a grain of salt, your mileage may vary, etc.
Can you share your temperature readings from inside the shed, with the generator running on load? Also, can you post a link to your exhaust fan? Thanks,
Very nice build! One of the best I've seen and I've watched a lot of videos. I live in central Florida, so I think I would really need a wood version fortified for a Hurricane. Ideally I'd like to have it operable during a hurricane so if the power goes out I can remote start the generator and I'm good to go.
Awesome stuff! Question- doesn't all that exhaust hose cause some sort of back pressure type issues for the generator? Like it's gotta push the exhaust all that way..
Yes, the longer the run and the narrower the pipe and the more turns, the more back pressure. I'm actually working on a version 2.0 of my exhaust pipe and muffler that opens out immediately to a 2" pipe instead of a 1" pipe, shortens the overall pipe length, and also uses some electrical metal conduit (EMT) 90 degree bend instead of the shorter 1" pipe elbow 90 degree bend. All of these should let it breath easier. Keep in mind that the muffler design was just a proof of concept to see if it would even work at all. It did work in general, but it definitely could be better. Also going to add more heat tape around the exhaust pipe itself to keep the shed temperature down.
The shed is actually designed to have the propane tank on the outside when running. I was just too lazy to do it for the video. The propane tank lives in the shed for storage, but you can move it outside when running it, and feed the hose back in through the same blastgate that the electrical cables go through. I do mention this in a later video where I go over frequently asked questions, parts lists, shed costs, etc.
There are several other videos on my channel about the design and later improvements to the exhaust and muffler. See links in the description or go to my channel for more related vids.
Agree - 1st Place Blue Ribbon design! Mike S. Thinks like me, the rockwool zig-zag (audio “egg crate” idea) may cut 2-5dB (depend press., temp. And amp “draw” or load). Super design!! Thank you!
I was an engineer for a company that designed huge generators outta massive diesel engine. For 2 companies. And designed Many enclosures. For a newbie good job.
Thanks for the encouragement. I certainly did a few things wrong on my first attempt. I corrected a few of them in some later videos, like enlarging the exhaust and updating the muffler a bit. Should definitely update the fans for better airflow, though. But it is probably good enough for the purpose it was intended to address. Thanks again!
Thanks. I'm uploading a new video today covering upgrades I did to the exhaust and trashcan muffler, along with an FAQ and parts lists for the shed and muffler. It should be available later today.
I just purchased a Suncast shed and my worry is the heat causing damage. Especially where the exhaust exits the shed due to heat transfer from the hose to the mounting flange. I must say though I am impressed with the video. It is giving me a better idea of what to expect with my shed if I do the same.
You might want to check out my later video, where I made a few improvements on the design. It also has parts lists, costs, Frequently Asked Questions, etc. I do discuss a bit about how the exhaust exits the shed, and slightly better design to reduce the risk of melting the plastic. ruclips.net/video/y3pUw408jCU/видео.html
Best solution I've seen so far. I am building a wood shed with many of the same principles used in commercial construction to deaden sound with goal of a 30-40 db reduction (similar genset with 90db base noise level). Most folks forget the intake and exhaust vents let out the sound/noise - using properly sized sound baffles is the correct approach. Also if you have sufficient air moving through the shed you can vent the exhaust directly into the shed, (assuming appropriate materials are used to prevent fire/melting), further trapping the noise and eliminating the need for an exhaust modification or shed exhaust port, the ventilation fan will serve that purpose. Great Job! Now if I could actually find rockwool sound board...
Nice job! If there's a power outage in your neighborhood noise will never be a problem because everybody would be running generators if they have them. The cops does not respond to generator noise complaints during power outages.
fantastic job, love the pneumatic wheels and the exhaust dustbin silencer. the only thing i would add as a keyboard observer is some foam noise absorbers on the lid and sides to break the sound up.i will soon be in the same position as i am trying to get a genny (long waiting list...) and will build a house for it too.i will be doing a room within a room on mine.
Thanks for the ideas. If you are interested in the parts that I used, I have several more videos in this series. (See the video description for links.)

The resistance created by the rigged exhaust system builds a lot of backpressure at the expense of reducing the sound and will increase the heat of the engine while running. I would imagine there are performance issues as well. I agree that these generators are too loud, but if you want longevity and don't have neighbors too close, I recommend allowing the engine to cool and breathe as designed by the engineers. Great video.
All good points, and I completely agree. Check out my later video on my Version 2.0 exhaust on my channel. I address a lot of the issues that this version 1.0 exhaust had.

i was wondering why no one would address the intake and exhaust cooling vent like you did until now. you understand sound travel! thanks for doing it and showing me that what i was thinking did work very well. i am going to tweak your design and make a box like yours when I heal from carpel tunnel surgery, i am going to use concrete hardy board instead of plastic walls
Good luck on your build. I also watched countless generator shed videos and always wondered why everyone was okay with all the noise coming out of the inlet/outlet holes in the shed. My experiment turned out better than I thought it would, and I'm sure there are better ways to do it and still have adequate airflow. The same thing with the trashcan muffler; I couldn't believe nobody had tried something similar, but I couldn't find anything else like it. Make sure you check out the later videos in this series, as I add lots more info on the parts I used, shed costs, and tons of improvements to make the shed and exhaust safer and better performing.
Great DIY build. I think you'll go threw a lot of those propane tanks if the powers out any length of time. Might consider getting a couple of 100lb tanks unless you have access to NG. Another thing you might want to add is a sail switch wired so if that fan should crap out it would cut off the generator before it over heated. That would get ugly before you knew about it.
I had built one like this out of pallets, then I got the idea of using sandbags last summer, so just to tinker with it. I used sandbags filled with dirt for the generator shed except the door and the hood which I retained from the previous shed made of pallet wood. I had plenty of rockwool board left over from the old shed. I am going to make a muffler like yours but with more sandbags
The sandbags sound like an awesome idea. I love it when folks can take some of these ideas and think outside the box for solutions. Well done! Make sure you check out the other videos in this series for some additional ideas. I cover the costs, parts lists, and other FAQs in a later video about my Version 2.0 Shed Exhaust. Also upgraded all the pipe from 1" to 2" to allow the generator to breathe easier. Check it out here: ruclips.net/video/y3pUw408jCU/видео.html
@@C5Tor If you use the sandbag idea make sure to use lose topsoil, it absorbs sound better than the soil from a deeper depth. The trash can muffler idea is very good, and you can also make it out of sand bags. I used the synthetic polymer material sand bags because I could not find any other material. I came across hemp bags that I used to replace some of the damaged bags. Hemp costs more but it outlasts the synthetic fiber bags. I only used rockwool on the door and cover. I should make a video one day.
BTW dont worry about clumps of grass roots in the bag they help to absorb sound. You dont want the contents of the sandbags to be too compact because then they would be just like bricks. Dont over engineer it
My HOA would be upset over the actual shed. Love the engineering that went into this.
Hoa. Sheep and their hoa s
Tell your HOA to pound sand…..😂😂😂😂
There's nothing worse then an HOA.

Overengineering is truly an art and a beautiful art at that...
Why do all that? Buy a quiet generator and not a cheap one.

I bet your neighbors really appreciate the effort you put into this. Sounds great and very quiet.
Or just buy an inverter generator, and it will be nice and quiet, reliable, they provide cleaner energy, and use less fuel. I do none of this and its very quiet.
I definitely wanted to buy an inverter generator, but nobody was building one that was powerful enough for my minimum requirements. Honda and Yamaha did not have enough power, and they were 4 times as expensive. After I made the shed, Harbor Freight came out with a Predator 9500 inverter that just barely has enough power. Still haven't seen a lot of inverter generators on the market that have enough power and support 240v, and definitely none that have dual fuel options.
They are expensive, for only twice the price Yamaha does make a cable for "twinning" two generators. This doubles their output, and what we got for our two. Means both generators are also small enough that you can pick them up and put them in the bed of the truck no problem, and yet still have decent output to run must-have items in the home during an emergency. Worked for about a week straight during the Houston flood when we lost power for 6 days. @@C5Tor
@@C5Tor When I decided to get a generator, the first thing on my list was NO GASOLINE. At the time that took out every inverter model on the market, it probably still does.

I am baffled on how baffles work
I'm no engineer, but I think it is similar to waffles, but baffles absorb sound instead of syrup. ;-)
That is HANDS DOWN, absolutely the BEST, gas/propane generator sound deadening shed build/review video that I've EVER seen on YT! I'm TOTALLY going to build one just like that! I'm currently using my chicken tractor to house my generator if/when we loose power and have to run the generator and it reduces the noise level at least 50%, but no where near as much as this shed does. I love the ingenuity of using the generator itself to run the fan that cools the shed! Absolute genius brother! Great video and I look forward to watching the build videos now. You've definitely earned my SUB with this video! Thanks
Thanks for the enthusiastic feedback! Stay tuned for some more videos as I upgrade some of the components of the exhaust from 1" to 2" to make the generator breathe a bit easier. I am a bit curious what a chicken tractor is, though. (Nevermind, I looked it up. But I was totally picturing a chicken driving a John Deere.)
I built same 5 years ago. But used two electric fans. Bigger exhaust pipe same shed but From Lowe's. Took truck plastic gas tank mount on back
25 gallon. With gas gauge use almost same cord from Walmart I also put extension on oil. Fill and drain from outside of generator house I used fire proof rock board inside for inside the walls . And key start on outside of generator house installed lights inside for nite time use light switch fuel gauge start and choke mounted on outside generator house. Hook up my own manual transfer switch next main power box easy on and off whole house power. This has been working just over 5 years with many power outages this guy did great job 🤔 but exhaust pipe to small can lead to engine over heating and burnt valve I also used vent covers from ac filter there big and provide lots of air. Key start and light switches , fuel gauge mounted inside water proof case normally was used to cover two outside wall sockets got the biggest one clear door on front when door is open lights come onthere can see fuel gauge and others that mounted in there.used switch for lights from car door interior lights
Sounds like a great setup with lots of convenient customizations for running long term. I wasn't quite that ambitious, as backup power is kind of the secondary function of this generator. I do agree on the exhaust pipe issue on my build. I'm working on version 2.0 of the exhaust setup today. I'm going directly to a 2" pipe to the muffler, and the new muffler has a lot more flow to it (a funky 4" x 8" spiral chamber in the muffler.) Doing some testing this weekend to see how it works. Crossing fingers! Thanks for all the tips!
@@C5Tor thank you. .my exhaust I ran straight out motor to outside with muffler at the end but used stock motorcycle muffler . Love trash can idea . Did you use fiberglass insulation in can I think empty can would make it louder. I also header wrap from advance auto to wrap pipe . Generator bought from harbor freight they must had a return because generator head was changed should have been 10 000watts but came home with 25 000. Watt. For $800. But loves gas my power out after hurricane 2 weeks ran generator whole time 24 7. But off for oil changes. 170 gallons of gas but also had ac on water heater lights had whole house power. .but I love what you did bring back lot of memories. .god bless 😊
Sounds like you got a great deal on that generator! I have another video on how I built the trashcan muffler. I'm actually working on a second video on my Gen II muffler with bigger pipe and better flow. Gen I was super effective at cutting down the sound, but probably had too much backpressure. Might have the new video out next week after some testing. Gen II muffler takes a different approach than the Gen I. Check out the Gen I video here: ruclips.net/video/jZpRSenXJAs/видео.html
This is a very impressive build. Good Job. Another way to keep neighbor's happy is to share some electricity with them. ...A while back a storm took out power in our neighborhood for several days, resulting in the need to run a generator several hours a day to keep freezers and refrigerators cool. I ran a mess of extension cords powering 6 refrigerators and freezers for two neighbors directly, and allowed others neighbors to store food items in fridge/freezers as well as plug in small electronics and coffee makers. This storm ended up being quite a good community building experience and all the neighbors were very grateful and very happy to have light, power and or coffee in the morning. One more tip I wish to share with like minded individuals is that when running things on a generator, it is good to know the load involved. A TV uses (80W), a laptop (50W), a cell phone charger (15W), a cable modem (30W), A typical box fan (80W), and old fashioned light bulb (100W), an LED bulb, (10W), a coffee maker (900W), a microwave (1200W), refrigerator (200-300W), a chest freezer (200W), Window air conditioner (500-1400W), and an Electric space heater (1500W). You do not need to remember all these values as they are legally printed on back of the device by the plug, but having a good solid understanding of what loads what devices are producing helps ensure you don't overload extension cords or the generator.
I Just finished putting together my set up. I would like to thank you for your post and some great tips. Looking forward to ERCOT dropping the ball again this winter. 👍😜

I’m in the process of putting together the same type generator shed. Your homemade muffler idea is next level ! Thanks for the inspiration - looking forward to your next video with more details. Thanks!
I've just uploaded another video about how I made the muffler. Link is here: ruclips.net/video/jZpRSenXJAs/видео.html
Soooo ligit
Nice, well-thought-out job and application of the "sound does not like to turn corners" rule.
Thanks. To clarify: sound will certainly go around corners. (Ask any mom who can hear her kid getting into trouble in the next room!) But that is mostly because the sound gets reflected from some surface. Hard, flat surfaces will reflect it the most. In my application, I tried to make sure that the reflective surface absorbed some of the sound and reflected as little as possible, so the sound had no direct (straight) route out of the box. Thus the "sound doesn't like to turn corners" rule was just my summation of the theory. Not sure if it is written down in any physics books in quite that way.
Great job what did it end up costing?
Thank you !! I will definitely be putting a set of "off road" wheels on my generator. The thing is a beast to move around. Many great ideas with the shed too. Generator thieves are a huge problem when there are long term power outages. Keeping things quiet makes you less of a target.
nice work! huge difference. A lot of people don't understand that the DB measurement is logarithmic, though the numbers don't appear to be that different it is actually a massive reduction with your work!! the fact that we can hear you perfectly clear while you are right next to the genny is awesome!!! now do a shop vac lol
That was great with some awesome considerations to flying below the radar and not draw attention to oneself
Very impressive...Great Job!
I agree with the previous comments. Excellent solution to quiet noisy portable generators.
the only drawback to this beautiful design is the distant the current has to travel and it will lose some of it's current because of this variable but --- hey -- so what -- it's quiet - and this to me - he accomplished 100% ... congrats ..
I believe I will do the same thing on my gen ... TY
:)
Totally agree. The location that I had to put the generator was not ideal. Unfortunately, there wasn't a good place to put it on the other side of my garage, where my electrical box was. So I just got the thickest cables I could get and went from there.
FrankenMuffler is brilliant - I’m definitely going to use that technique for my upcoming gen shed build.
I have two neighbors that need this. We recently had a 10 day power outage...both of them ran their generator 8am to 8 pm! I just about lost my mind!
Great work!!! Sound discipline will be HUGE during SHTF.
Pretty cool setup. The only recommendation I would have is to remove the propane tank from enclosure . As the tank heats up it builds pressure. If the pressure reaches its limit the tank has a blow off valve. If it blows off inside that enclosure you will turn that enclosure into a large expl*sion.
If angles had been created with the rock wool, I wonder how much even more improvement would have been realized. Great build.
I've just completed a shed based on your design, after having all the pieces lying around for well over a year. I still have some fine tuning to do and I'm thinking I may add a second fan on the intake side, but WOW is it ever effective. I don't think there is any premade enclosure on the market that could do as well. My Champion 100416 went from 90 dB+ at 10 feet to 70 dB and that is without side baffles. Just leaning a Rockwool panel in front of the intake drops it to 68 dB. One mod I did is replace the stock gas struts with ARANA struts rated at 60 lbs ($22 from Amazon). This is a great upgrade; not only does the lid stay up under the weight of all that Killmat, but you can place it at a good angle to reflect rain or open all the way to vertical. Thank you so much for all of the time and effort you put into sharing your approach with the world. Salute!
Sounds like a great build. I wish I had upgraded the gas struts as well, as the stock ones barely hold up the lid with the added weight. Thanks for sharing!
Good job. I especially liked the vent baffles which is an area most other generator sheds fail to address. Also, great job on the muffler. You can't beat volume for attenuation and you have plenty.
Thanks for the inspiration.
Just finished building a box for mine used three blowers to remove the huge amount of heat.
This is awesome. I love the way the generator is protected from the elements and at the same time the noise levels are low enough to not be a nuisance. Great job with this build sir.

Honestly, I didn't watch the video or read many comments, but I'll just tell you that I saw the LPG tank and reg inside the box and it jumped out as something I wouldn't have done. Codes require clearances around natural gas regs (pre-meter) to things like windows, vents into buildings and air inlets to appliances. If the diaphram in the reg has a sudden major failure (rare , but it can happen) , you want that leaking gas to go outside and away from any potential ignition sources. Plus the tank just takes up room and doesn't make any noise anyway. I know bbq's have the tank/reg right next to the flame, but it's still something that most people don't think is an issue until they have what could be a very serious problem. At least that reg you have on your tank is a 2 stage.
Legitimate points. The shed is setup so that you can easily move the propane tank outside of the shed and run the hose back through the blast-gate on the left, along with the electrical cables. And yes, BBQs have the propane tank literally inches from the open flame as well. Leaking propane is never a good thing. I discuss these issues in my later videos on the exhaust and shed.
That’s an awesome set up. You should think about maybe selling the box as a kit to people who want a quiet generator enclosure. I bet it would sell great!
I would by one for sure because I'm getting my generator hookup installed next week and buying me a generator as well
Good idea using the trash can. For permanent stationary engines I have seen people use 55 gallon drums sunk level with the ground full of rock with the exhaust pipe 3/4 of the way down and they are almost dead silent.
The BEST sound/fireproofing solution system in a plastic horizontal shed that I have seen!
I intend to build a similar setup for a smaller generator and had planned to make my own 'comfort board' type insulation out of fiberglass batts and 1/2" hardware cloth fencing. This is a huge improvement over what I wa going to try
My only concern is that by extending the exhaust as far as you did you may damage the valves on the engine from increased backpressure and heat.
I don't think it'll hurt the valves. We've added exhaust extensions to almost every engine you can think of and never had an issue. Hope this helps.
I think if you make sure to increase the diameter of the exhaust pipe, backpressure shouldn’t be an issue.
There are several more videos in this series. I cover how I built the trashcan muffler in the Exhaust Version 1.0 video (view it here: ruclips.net/video/jZpRSenXJAs/видео.html). Then I did a later video on my Version 2.0 exhaust on my channel, which has quite a few improvements over the version 1.0 setup, including upgrading the pipe to 2" diameter. The newer video has parts lists, shed costs, and other Frequently Asked Questions. Check it out here: ruclips.net/video/y3pUw408jCU/видео.html
Not a bad little shed. Sound does actually have no problems with corners. It uses diffraction and reflection through a narrow aperture or across an edge Just make the edges and passage ways aren't that narrow.
Nice work. Good think-through process.
That's some impressive noise reduction. And all done without breaking the bank!
I went through this with my camper. my final solution was a 7k Honda in a box. The inverter allows the engine to run much slower.
All of his work seems successful, good job. The Honda is portable, but over $3500.
Would have loved to use the Honda, but it was too small (capacity-wise) and way too pricey.
Cool dude. I just bought the exact same generator from Amazon. I plan on trying to set it up with Propane and a switching breaker box and see if I can get it to work like a "stand-by generator" to turn on and off automatically. Using the propane (for convenience ) I won't have to worry about carb clogging and fuel degeneration.
Impressive. I've found out I'm spending way more than I had anticipated for my generator.
I wish I saw this before my build, good job 👏🏾 👏🏾👏🏾👏🏾👏🏾
this looked like a GREAT project. Outstanding job.... super clean.
For a much quieter generator, invest in one that turns 1,800 RPM's instead of an 3,600 RPM. Also the exhaust being curled would cause restrictions
Always nice to have neighbors who are courteous when it comes to sound levels...
I do not have such neighbors.
Their kids alone would drown out the sound of many generators running in the open.
Then the constant leaf, grass blowing and pressure washer...
This is an extremely nice setup, and I will definitely be doing the same
Great design, well thought out. Glad I found your video since I was looking for ideas
I only use my generator during outages so I just have a wooden shed to store it in but no sound proofing. I also have a battery trickle charger to keep the generator battery topped off, the last thing I want is to mess with a pull string during an outage, here it is usually a snow storm or wind storm like last week in Seattle area we had about half a day without power so I kicked off the generator but would be pissed if the battery was dead. Nothing like Propane, no more expired gasoline or blocked carbs just make sure you have enough propane. I have a 500lb tank since I use propane for heating as well so I have the generator hooked up.
This is awesome! Glad I saw this! I live in a pretty compact area so this would be perfect! Adding to my list and I love the baffles!
Glad it was helpful!
Great job with the sound deadening!
One thing I would like to point out is I would move the propane cylinder outside for safety, preferably to the yard maybe by running some hardline.
I discuss this in a later video about my 2.0 exhaust setup. Check out my channel for more vids on this subject. The shed is designed so that I can put the propane outside and pass the hose back in via the blast gate.
Great test! I ordered the exact generator as yours. I will be building a shed using the rock wool as well. Congratulations on a successful build.
Good job that's quieter than my dishwasher!
Great use of a cheap blast gate! This is the best design I've seen so far on RUclips. I have been kicking around the idea of building one for about five years now. I just haven't done it. There were too many unknowns about how well my design would work. I even purchased a metal bicycle/ lawnmower storage box to use for the shell. I had planned to use 1 1/2" fiberglass duct board, but I think rockwool is even more sound-dampening or absorbing, whichever is the right term. I am really impressed with the galvanized garbage can turned into a muffing chamber.
Oh, and also the fan outlet box. Did you put a couple baffles in it to route the sound in a few different directions before it exits? Again, Great Work, Sir!
Great job engineering this generator cabinet. Sound reduction is impressive!
Wow ! You did a superb job on your generator sound suppression box. I don't think I've seen a better designed one anywhere. Are you an engineer ? Big thumbs up.
I did pretty much exactly the same without the muffler. I also added a solar battery tender to keep battery topped up and a solar charged LED strip to bottom of lid in case I need to be starting it up in the dark.
I discuss this very question in a later video on my Version 2.0 exhaust. The LED strip is a good idea. The video also has parts list, shed costs, and other Frequently Asked Questions. Check it out. ruclips.net/video/y3pUw408jCU/видео.html
Great design! Since the actual shed walls are plastic, what if you drilled some small holes in each section and filled them will some type of thick fluid mixture to help beef up the walls? Could you use concrete maybe?
i thought about that too
Thank you exactly what I am looking for! I have an off grid situation that is being ruined by noise from generator!
Congrats on a very well thought out design and build! I am in the design process now and will definitely be utilizing a number of your insights! Which Suncast model did you use? I think it's the 70 cubic foot model but I can't be sure. Thanks!!
Yes, I believe it is the 70 cu. ft. model. I bought it "used" off of craigslist. The original owner had purchased it but never put it together, so it was still in the box.
It appears to be the BMS4700 "Stow-Away" Horizontal Shed.
If so, I paid $480 for mine. @C5Tor got a steal! :-)
Great idea! Plus, if you’re storing it there a thief probably isn’t gonna think anything of real value is there. 👍🏼
Great job. This is the route that we’re going to have to take since we live in an HOA neighborhood. Have you run the generator loaded to the house? Also, have you done any testing to determine how long your propane tank will last?
We tested the generator interlock when I had it installed. Ran a moderate amount of household items. But the generator won't be big enough to run things like my air conditioner or oven. Microwave is fine. It should keep my fridge cold and the internet running. Don't really know how long a tank of propane will last yet. Still in the testing phase. Specs say the generator can last up to 17 hours on the 6.6 gallon gasoline tank, and about 11 hours on a full 20 lb. propane tank, depending on load, of course. Take that with a grain of salt, your mileage may vary, etc.
most quiet I've seen and I have watched LOTS of videos!
Can you share your temperature readings from inside the shed, with the generator running on load? Also, can you post a link to your exhaust fan? Thanks,
Very nice build! One of the best I've seen and I've watched a lot of videos. I live in central Florida, so I think I would really need a wood version fortified for a Hurricane. Ideally I'd like to have it operable during a hurricane so if the power goes out I can remote start the generator and I'm good to go.
Awesome stuff! Question- doesn't all that exhaust hose cause some sort of back pressure type issues for the generator? Like it's gotta push the exhaust all that way..
Yes, the longer the run and the narrower the pipe and the more turns, the more back pressure. I'm actually working on a version 2.0 of my exhaust pipe and muffler that opens out immediately to a 2" pipe instead of a 1" pipe, shortens the overall pipe length, and also uses some electrical metal conduit (EMT) 90 degree bend instead of the shorter 1" pipe elbow 90 degree bend. All of these should let it breath easier. Keep in mind that the muffler design was just a proof of concept to see if it would even work at all. It did work in general, but it definitely could be better. Also going to add more heat tape around the exhaust pipe itself to keep the shed temperature down.
Im about to build mine when everything arrives. I think im going to do the same thing. I think this is the quietest build ive seen on here.
Very clever set up.
very good build. Now I know what I got to do. The only thing different is I'll run my propane/gas tank out side the shed. Thanks for the video.
The shed is actually designed to have the propane tank on the outside when running. I was just too lazy to do it for the video. The propane tank lives in the shed for storage, but you can move it outside when running it, and feed the hose back in through the same blastgate that the electrical cables go through. I do mention this in a later video where I go over frequently asked questions, parts lists, shed costs, etc.
Very smart ideas!... very quiet and hardly noticeable, thanks for sharing!
Very nice setup!
Brilliant work I’m sure your neighbors are very pleased and so should you 9:03
That is pretty impressive.....I could see potential for a triailer setup that would be beneficial when out and about. Nice work man!
Fantastic work. I've been binge watching videos to do this for my Duromax 12k watt generator. Yours turned out amazing.
There are several other videos on my channel about the design and later improvements to the exhaust and muffler. See links in the description or go to my channel for more related vids.
@@C5Tor Awesome. I'll check those out as well. Love my generator but man it is noisy.
Agree - 1st Place Blue Ribbon design! Mike S. Thinks like me, the rockwool zig-zag (audio “egg crate” idea) may cut 2-5dB (depend press., temp. And amp “draw” or load). Super design!! Thank you!
I was an engineer for a company that designed huge generators outta massive diesel engine. For 2 companies. And designed Many enclosures. For a newbie good job.
Thanks for the encouragement. I certainly did a few things wrong on my first attempt. I corrected a few of them in some later videos, like enlarging the exhaust and updating the muffler a bit. Should definitely update the fans for better airflow, though. But it is probably good enough for the purpose it was intended to address. Thanks again!
Great job !!! I may try something similar...
This is the best video in generator sound mitigation
Thanks. I'm uploading a new video today covering upgrades I did to the exhaust and trashcan muffler, along with an FAQ and parts lists for the shed and muffler. It should be available later today.
I just purchased a Suncast shed and my worry is the heat causing damage. Especially where the exhaust exits the shed due to heat transfer from the hose to the mounting flange. I must say though I am impressed with the video. It is giving me a better idea of what to expect with my shed if I do the same.
You might want to check out my later video, where I made a few improvements on the design. It also has parts lists, costs, Frequently Asked Questions, etc. I do discuss a bit about how the exhaust exits the shed, and slightly better design to reduce the risk of melting the plastic.
ruclips.net/video/y3pUw408jCU/видео.html
Best solution I've seen so far. I am building a wood shed with many of the same principles used in commercial construction to deaden sound with goal of a 30-40 db reduction (similar genset with 90db base noise level). Most folks forget the intake and exhaust vents let out the sound/noise - using properly sized sound baffles is the correct approach.
Also if you have sufficient air moving through the shed you can vent the exhaust directly into the shed, (assuming appropriate materials are used to prevent fire/melting), further trapping the noise and eliminating the need for an exhaust modification or shed exhaust port, the ventilation fan will serve that purpose. Great Job! Now if I could actually find rockwool sound board...
Nice job! If there's a power outage in your neighborhood noise will never be a problem because everybody would be running generators if they have them. The cops does not respond to generator noise complaints during power outages.
That’s sum professional grade work and the sound reduction outcome was unbelievable great job 👏.
fantastic job, love the pneumatic wheels and the exhaust dustbin silencer. the only thing i would add as a keyboard observer is some foam noise absorbers on the lid and sides to break the sound up.i will soon be in the same position as i am trying to get a genny (long waiting list...) and will build a house for it too.i will be doing a room within a room on mine.
Thanks for the ideas. If you are interested in the parts that I used, I have several more videos in this series. (See the video description for links.) One of the later videos is on my Version 2.0 exhaust, which has quite a few improvements over the earlier version 1.0 setup.

You are the best kind of nerd. Thank you for making this video.
That may be the best compliment I've received yet! Love it!
great job. thanks for sharing
Whoa. That's really great.
The resistance created by the rigged exhaust system builds a lot of backpressure at the expense of reducing the sound and will increase the heat of the engine while running. I would imagine there are performance issues as well. I agree that these generators are too loud, but if you want longevity and don't have neighbors too close, I recommend allowing the engine to cool and breathe as designed by the engineers. Great video.
All good points, and I completely agree. Check out my later video on my Version 2.0 exhaust on my channel. I address a lot of the issues that this version 1.0 exhaust had. The newer video also has parts lists, shed costs, and other Frequently Asked Questions. Check it out here: ruclips.net/video/y3pUw408jCU/видео.html
The shed is pretty astonishing. But when I saw the boxes on the side… it was baffling!!
i was wondering why no one would address the intake and exhaust cooling vent like you did until now. you understand sound travel! thanks for doing it and showing me that what i was thinking did work very well. i am going to tweak your design and make a box like yours when I heal from carpel tunnel surgery, i am going to use concrete hardy board instead of plastic walls
Good luck on your build. I also watched countless generator shed videos and always wondered why everyone was okay with all the noise coming out of the inlet/outlet holes in the shed. My experiment turned out better than I thought it would, and I'm sure there are better ways to do it and still have adequate airflow. The same thing with the trashcan muffler; I couldn't believe nobody had tried something similar, but I couldn't find anything else like it. Make sure you check out the later videos in this series, as I add lots more info on the parts I used, shed costs, and tons of improvements to make the shed and exhaust safer and better performing.
@@C5Tor I wonder why nobody has built one out of cinder blocks, fire proof, easy to build and soundproof , Just a thought
yea I really like the 20000 degree of the insulation, too. Thanks for sharing.
Probably more like 2000 degrees, but I agree it is pretty cool stuff.
that shed is mint. You could also dry stuff out in there too.
Excellent project!!!
Interesting. It’s the best shed mod I have seen. 👍🤙🏼💪
nice performance !
That is an awesome shed build
Love what you have done here!
Nice Idea !!!
Great job.
Great DIY build. I think you'll go threw a lot of those propane tanks if the powers out any length of time. Might consider getting a couple of 100lb tanks unless you have access to NG. Another thing you might want to add is a sail switch wired so if that fan should crap out it would cut off the generator before it over heated. That would get ugly before you knew about it.
That's dope!
Blessings From Texas🤠
Brilliant! I think you should market this and make soundproofing kits. Maybe sell the franken-muffler as your own design.
I had built one like this out of pallets, then I got the idea of using sandbags last summer, so just to tinker with it. I used sandbags filled with dirt for the generator shed except the door and the hood which I retained from the previous shed made of pallet wood. I had plenty of rockwool board left over from the old shed. I am going to make a muffler like yours but with more sandbags
The sandbags sound like an awesome idea. I love it when folks can take some of these ideas and think outside the box for solutions. Well done!
Make sure you check out the other videos in this series for some additional ideas. I cover the costs, parts lists, and other FAQs in a later video about my Version 2.0 Shed Exhaust. Also upgraded all the pipe from 1" to 2" to allow the generator to breathe easier.
Check it out here: ruclips.net/video/y3pUw408jCU/видео.html
@@C5Tor If you use the sandbag idea make sure to use lose topsoil, it absorbs sound better than the soil from a deeper depth. The trash can muffler idea is very good, and you can also make it out of sand bags. I used the synthetic polymer material sand bags because I could not find any other material. I came across hemp bags that I used to replace some of the damaged bags. Hemp costs more but it outlasts the synthetic fiber bags. I only used rockwool on the door and cover. I should make a video one day.
BTW dont worry about clumps of grass roots in the bag they help to absorb sound. You dont want the contents of the sandbags to be too compact because then they would be just like bricks. Dont over engineer it
This is some incredible engineering actually haha, great video!
