It looks really good! Too bad it didn't make much of a difference. Those briggs motors are just simply loud. I know folks that have tried to quiet them down with little luck. You get an A for effort though!
I have a 6500/7500 PowerMate genny in a Suncast dual trash can shed. I've been considering altering the muffler to quiet it down, but as noted, these rigs are LOUD, period. Many YT videos confirm this...thank you for sharing your test! It's not so much the exhaust. Some guy has a video up that quiets a genny 10x in 10 seconds.....he lays plywood sheets all around the genny. Insulation/sound deadening seems to be the key. I'm guessing my next move is a sound insulation attempt. The way my Powermate is set up, the exhaust is on the 'left side' along with recoil pull handle. Power panel on the 'right'. The exhaust points out one of the two shed doors, the other I can close along with the roof of the shed. The exhaust door will always have to be open during operation, which is ok with me. Hopefully, with sound deadening material applied to all interior surfaces the engine noise will drop some.
Studio DaVeed The exhausts on those Tecumseh engines aren't quiet at all. A better exhaust would definitely help, but air cooled engines aren't that quiet to begin with. The engines would be much quieter if it was suspended in some springs and rubber pads to absorb the vibrations. I am planning on building a generator that will run at a lower 1800 rpm instead of screaming at 3600 rpm using an 18 HP Onan engine. The lower rpm will be far less noisy. I will be using small springs with rubber pads for the engine mounts to keep the noise down. I am using the stick mufflers but I'm welding pipes to redirect the exhaust into another resignation chamber to make the exhaust sound like a steady "hmmm". Lastly, the entire setup will be put into a wooden box with sound dampening material on the inside. The exhaust will exit out the side of the box with thermal insulation to protect the wood. I have a 10kW generator head rated at 3600 rpm that is shaft driven so I will have to use 3 individual v-belt pulleys at a 2:1 ratio.
Lean a piece of plywood against it with the plywood facing you, makes a huge difference in the noise that makes it to you. Trick we did when I was framing houses.
I've been wondering this my whole thinking life ... how a 70's Cadillac with a huge 200hp v8 can be nearly silent at idle, but a cycle or small engine always has to be annoyingly loud - good on you for trying this and putting it together
Air-cooled vs watercooled motor, air-cooled engines have very thin metal around the cylinder vs a watercooles car engine, that reduces alot of the combustion noise, I'm sure the water running through the block helps reduce it to. Also, having a 12-foot-long exhaust pipe helps too, having the engine enclosed under the hood helps too.
Need to extend the length exhaust pipe going into the muffler and use a different muffler size to the CC of the motor. That mufflers not giving it enough back pressure to muffle it down. Try like a muffler off a small little motorcycle or something.
Thank You!!! I was going to try this on my emergency Genset. My friend built a plywood box with air holes and glued blue styrofoam to the outside and it did make his quieter, looks like shit though and is big to store. Great info, saved me from trying it.
I have a generator that sounds like a harley. Added a 2 in. X 2 foot flex muffler tube and pointed it to ground. Quieted it dwn i would say by almost half.
Do not forget about generator safety ruclips.net/video/I1jT3ANENvI/видео.html keep in mind that portable generators can be dangerous if not used carefully. Especially it’s important to keep children safe when you’re using portable generators. Thank you. Stay safe
You are not hearing the sound of the exhaust you are hearing the sound of the engine. It is not a very well balanced engine. Lots of vibrations lots of noise.
There are two things to consider when trying to quiet down a small engine. #1 The amount of metal and thickness of the crank case and cylinder and cylinder head. Small, air cooled, engines have very little metal in the engine housing itself so a lot of the combustion noise is actually coming through the walls of the engine. This can be addresses by enclosing the engine in a sound dampening housing. however this is problematic with air cooled engines. #2 No matter how quiet a muffler claims to be, it is greatly influenced by the length of exhaust tubing. The longer the exhaust tubing the quieter the the sound. The exhaust noise is greatly reduced by the distance and turns and surfaces in which the exhaust, and pressure wave, has to transverse.
Thanks for watching and commenting. I’ve seen a lot of generators burnt up at the race track with not enough air to cool them. I hope to do more experiments on it soon. Have a good one

It would take 8 years 7 months and 6 days to heat up a cup of coffee just by yelling at it. Sound wouldn't be to efficient producing energy. I'm pretty sure if you harnessed every sound a generator makes in the whole US you might have something decent.
miggs225 there are so many factors to consider. In car, sound gets absorbed in a long exhaust pipe. The longer the sound travels in an enclosed pipe the more it looses the energy and finaly calms down by the time it passes through the muffler which reduces it further to almost quite. The exhaust pipe is purposely hang on rubbers which also helps to absorb the vibration from the moving gas that comes out with a pounding force. Secondly, most genders are two strokes engine.the interval between the firing in the cylinders is very long. If a genset is made with 6 cylinders, it will produce less sound bkoz the firing will happen at close intervals hence sound will come out smooth like bruuuuuuuuu than braaarrrrrrr Thirdly, the sound doesn't just come from the exhaust pipe alone but also comes out directly from the thin cylinder walls. The only way to contain the sound is to cover with a sound proof box.
95% of all the noise comes from all the mechanical parts while it's running. Put an insulated box around it, put an inlet fan to keep it cool and feed the carburetor. Take that exhaust from the muffler and run it towards the ground. Put some cinder blocks around the exhaust near the ground and you'll hear a huge difference in noise level. Thanks for sharing. Been there done that test. Best Wishes & Blessings. Keith Noneya
Thanks for watching and commenting. I have to move the generator around to different cow pens when we have power failures. I really enjoy trying to make things work better for us here on the farm. I agree with the most of the noise being mechanical. Have a good week.
A company I worked for a long time ago actually bought a device to pick up the sounds in an exhaust, delay it, and play it back thru a speaker in the exhaust 180 out of phase to cancel the noise. Not my project, so don't know how well it worked, but based on this video I suspect there was a reason it was just sitting on a shelf in the conference room.
I don't have very much experience with generators. However, as a semi-retired auto mechanic. I know that muffling the INTAKE of an air compressor does wonders for quieting them down inside the shop. In fact, the only difference I've noticed on standard vs. ultra quiet compressors is the intake has been muffled on the ultra quiet ones. Might be something to try out on a future video. Also, you wouldn't have to worry as much about heat and that would free you up to use a wider variety of materials. Just some thoughts. I just found your channel and have subbed.
Lot of work, but we learned. Maybe the way to get quiet is a sound-absorbing box around the generator, and a pipe (not directly connected) like a chimney, to carry the sound up toward sky.
Most of the noise from those type of small engines comes from the engine itself since nearly all of them run at 3600rpm. I think an absorption muffler like a glasspack would be quieter. Most of those car mufflers have passages and chambers that are too big for a small engine to slow the exhaust flow and direct it to quiet it down enough.
100% guilty of liking this video, subscribing and hitting that bell just cause I appreciate a good install. AND that's one hell of a southern draw you got there man! #ifitaintsouthernitaintRIGHT!!
AMonsterNut Thanks. We’re going to do more experiments on it. We converted a old round baler into a rebaler,dirt track racing vids drone videos. Have a good week
I had a single stage air compressor for airbrushing. I put in a sealed container with sound deadening material on the inside. It worked perfectly but the only issue was heat being stuck inside the enclosure. The compressor was way hot after an hour of use. I'm sure there is a way to do this without any bad side effects.....
Honesty is lacking is most reviews. You are completely honest and objective and I for one respect that. Thank you for the information. I have a large Winco Generator with a Honda engine. It’s as quiet as it can be but as you said, the actual engine noise is louder than the muffler.
T.T. - wrong because of what? The muffler he used is a baffled chamber. A flow through muffler uses a different technology that absorbs sounds without baffles. Is that what you’re suggesting? I saw that explanation on another video but not sure if I understand it completely. I have a chipper shredder that mostly runs wide open when it’s working and it seems much louder than the previous Craftsman chipper shredders I’ve had.
@@100pyatt put a little re-bond carpet padding or horsehair carpet pad onto the plywood and that should make a very good noise insulator, just keep enough distance between the padding and anything hot. Leave the top open and raise the bottom just enough to get air circulation. You can get clean used carpet pad free from most any carpet shop as its recycled and they probably wouldn't mind if you pulled some from their recycle bin as long as you didn't leave a mess
Make your own muffler, just larger, use a 55 gallon drum lined with something. Might sound deeper. Most sound probably come from engine not exhaust. Put it in a doghouse or shed with exhaust outside shed.
I agree with the other poster, you get and A+ for the effort. That muff is thin sheetmetal, the exhaust "pop" flows into it and bang, like a drum. You could try a couple of old Cadillac muffs in series from a junkyard, I think they'd quiet the beast.
Thanks for doing this, I have been contemplating doing the same thing! You saved me the exact amount of time and money you spent on this experiment. Thanks again, I really appreciate it.
I am always amazed that so many people believe the problem with excessive generator noise is from the discharge of exhaust. While improving exhaust muffler application will have some minor impact. The vast amount of noise is being produced by the MECHANICAL ACTION INSIDE THE ENGINE. The MOVEMENT and ACTIONS of the Valves, springs Rod(s) Crankshaft and Piston(s) DEVELOP the MAJORITY of the NOISES HEARD The Engine case acts like a “bell” in amplifying and distributing these sounds OUTWARD FROM THE ENGINE AT GREAT VOLUME. A better approach would be to construct or apply an insulated cover for the WHOLE UNIT with allowances made for operating temperature and exhaust gases. But just throwing a muffler on it, is not the answer.
You need to shorten the lengths of Black Pipe! You want to have the muffler as close to the Engine as possible. You are getting nose from the Engine Resonating through that long length of black pipe, so by the time it gets to the muffler it's not really doing anything. You have the right idea, just need to make some minor adjustments.Also use a motorcycle muffler instead of a car muffler.
I always wondered if that would work. I guess now we know. Thank you for doing this video! **In the Army they had tactical quiet generators; it was basically just insulation surrounding all the generator with slots to allow for cooling/air...
I'd suspect a motorbike muffler would be better matched to this size engine, they also put rubber bungs in between the fins to deaden mechanical ringing noise on air cooled motorbikes.
I did this a few years ago with a Duramax and I found that if I put a muffler on the intake as well and put the air filter at the beginning of the muffler on the intake as well as having the muffler on the exhaust it was quite a bit quieter around 55 DB
Hey pal. Stopped in to support and say hello. I met you in one of the streams I follow for sure. When I first saw you putting that on I was like "WOW THATS A GREAT IDEA!!!!"... Part of me was a little bummed when it wasnt quieter. Very cool to try it though. Loved watching it. I was excited to see if it worked. hahaha Thanks for sharing.
Thanks for watching and commenting. Being honest is the only way I know. I still want to try a few more experiments on it soon as I get time. We’re busy on the farm. Have a good one
The resonator in an exhaust is tuned to a specific engine speed to reduce volume at that frequency of exhaust pulses. Car exhausts usually have a variable resonator that opens up at high speed (pressure activated) that offers a second tuning for the higher frequency. The small engine is probably running at a lower RPM than the resonator is tuned for. I'd try using a scooter exhaust. I doubt if a motorcycle exhaust would have much effect, either, since they're usually tuned for higher RPM ranges.
That's a good thought but, the engine is connected to the generator at a 1-1 ratio. So the engine is set to run at 3600 rpm (which is around or above the resonate frequency of most mufflers) to provide the 60 HZ electrical output. My theory is that the 3/4" pipe connecting the muffler to the engine is too small, therefore keeping velocity too high. I think had he used the short run before the turn to put a larger diameter pipe (like 1-1/4 or 1-1/2) then reduced back to 3/4, would lower velocity and allow the pressure waves to react against one another. A lot of automobiles have this very thing (a resonator) usually behind or built into the Cat.
The vast majority of sound on a conventional generator is from the engine internals and the actual genset on them. That’s one of the reasons inverter generators are so quiet.
Yes, the intake makes noise. Use this muffler for the intake. For exhaust, as soon as you can, increase the pipe to 1.5, then flex pipe to a glass pack muffler mounted with rubber hangers. Or just put a plywood cage around the generator (walls angled in just a bit)
I did the same thing to one of my generators. Didnt make it a bit quieter. I think most of the sound actually comes from the generator rather than the motor considering gocarts have the same motor and arent nearly as loud.
That's interesting findings. I retrofitted the stock muffler from my Triumph Speed Triple motorcycle to work on a Generac generator with the same engine and it's much quiter than the factory muffler. Perhaps the automotive muffler is too high flow for effective sound deadening on this application.
Much of the noise you hear from those motors comes from the exhaust gasses impacting the exhaust pipe. The pipe leaving the motor is too restrictive. What if you opened up the area the exhaust goes into right at the cylinder head? Use a flange unto which a larger pipe can be welded to. Taper out from the exhaust flange so you can still bolt everything up. It still might be noisy bit give it a try.
Can assure you it works very well but learned the hard way about over insulating exhaust because had a huge build up of carbon in the cylinder & started running rough after long hours of operation ended up having to pull head off & clean piston & valves but other than that its the way to go.
Dude,dig a hole on the ground at lest four feet deep and extend the exhaust pipe seven feet or longer, then place it on the hole and fill it with rocks the size of golf balls and then on the surface, a foot and a half of sand up to ground level!👍
You are a man of heart and soul. A valiant effort! Better luck on the next one. I might suggest an old motorcycle muffler that has a baffled inside. You can find them in old salvage motorcycle parts shops. They work very well for bike exhaust. The baffle does all the work. Give that a try. Mike in Colorado
Just get another reducer a piece of pipe to go in between at least 10" long and stuff it with the steel wool. Put a reducer on the end and a short piece of smaller pipe.
We Bury our gen in a 6 by 6 hole with lid that has plenty ventilation and a fan. Also the hole is lined with polyethylene Foam board and lid as well. When closed we can barely hear it. 👍
During #HurricaneKatrina my neighbors ran generators, while the rest of us had no pwr. Jeebus those things were loud! Then one night the noise stopped. Someone stole them.
That is one heck of a muffler job! AAA+ for effort! I tried using a car muffler on mine one time. I have the same exact generator except mine is called a “Sears Companion”. DeVILBISS made these for Sears. it did not make a huge difference, but it definitely helped. I wound up putting a factory muffler back on it but I am going to try to find a larger muffler that’s more appropriate for a generator.
Hey, I hope you never got rid of this generator. Those brushless alternators are awesome! I know the engines are loud, but a car muffler, and some sound block paneling can help.
Thanks for watching and commenting. I still have it in my shop. I have not use it sense this video. The car muffler is still on it. I want to try a couple more mufflers on it.
The most important thing is vibration control. Right off the exhaust port I used a Stainless Steel exhaust flex pipe (with SS braid on the outside) to isolate the engine from the solidly mounted exhaust as any weak point between the two will fail quickly, as in the aluminum engines exhaust port/mount breaking apart.
This is why Onan generators made for RV's are 4 pole generators. 4 pole generators only have to run at 1,800 RPM to have the necessary 60Hz frequency that we use in the United States. Lower RPM = less noise. The downside is that it takes an engine twice as big to produce the same power needed at 1,800 RPM instead of 3,600 RPM. I suppose if you had a belt driven 2-bearing 2-pole (3600 rpm) generator head, you could use a larger engine and run it at 1,800 RPM, but use a pulley on the engine that is half the size of the one in the generator. For example, a 6" pulley on the generator and a 3" pulley on the engine. That would turn the generator twice as fast as the engine. 1800 x 2 = 3600. The problem with doing that is that you might have problems with the engine getting too hot, since its air cooled and designed to be run at 3600 rpm under load. But that's just a possibility it may not be a problem. The bigger issue is that generators like the one in this video and most other portable geners, are a single bearing (on the rear) type and have to be directly connected to the engine VIA a "tapered" crankshaft in the engine. The generator uses the rear crankshaft bearing on the engine as its "front" bearing. Thus requiring you to rig up a v-belt pulley driven tapered shaft mounted on a pillow block to convert the generator to a belt driven unit. Lot of work and expense.. And then you still have a 3600 RPM generator, which won't last as long as a low speed generator will. My suggestion to anyone seeing this would be to just get an Onan RV generator. You can get them in gas, diesel and propane configurations in all kinds of sizes. Check Craigslist before ebay, people on ebay think those generators are worth 3 or 4 times what they're really worth.
Good try but the car muffler had little effect because it is not designed or "tuned" to the specific note produced by your generator motor. Mufflers employ some fairly exotic engineering in their construction to deaden and cancel the noise produced by car and truck engines. Remember what a fully unmuffled big old V8 before catalytic converters sounded like and how quiet those cars could be with the muffler intact (especially when they were new and the muffler not half rusted out). Best wishes!

Most of the noise from those type of small engines comes from the engine itself since nearly all of them run at 3600rpm. I think an absorption muffler like a glasspack would be quieter. Most of those car mufflers have passages and chambers that are too big for a small engine to slow the exhaust flow and direct it to quiet it down enough.
I agree . Thanks for watching and commenting. Have a good one
100% guilty of liking this video, subscribing and hitting that bell just cause I appreciate a good install. AND that's one hell of a southern draw you got there man! #ifitaintsouthernitaintRIGHT!!

Bummer dude! I was hoping it would make it quieter as well. Only option left is a soundproof enclosure.
Bennet Fox thanks for watching. We’re going to do more experiments on it. Have a good one
I had a single stage air compressor for airbrushing. I put in a sealed container with sound deadening material on the inside. It worked perfectly but the only issue was heat being stuck inside the enclosure. The compressor was way hot after an hour of use. I'm sure there is a way to do this without any bad side effects.....
Heyy...You gave it a heck of a go at it... Wish it worked for ya. We lose power alot here in southwest Virginia and I'd love to quiet mine down....

Random RUclips recommendation brought me here but thank you for an honest video. You tried something, it didn't work, you uploaded anyway. Respect.
More test to come
Honesty is lacking is most reviews. You are completely honest and objective and I for one respect that. Thank you for the information. I have a large Winco Generator with a Honda engine. It’s as quiet as it can be but as you said, the actual engine noise is louder than the muffler.
Thanks for watching. I still plan to do more test on it soon. I’ll post them soon as I can. Have a good one
Wrong type of muffler.
T. T. Thanks for watching.
T.T. - wrong because of what? The muffler he used is a baffled chamber. A flow through muffler uses a different technology that absorbs sounds without baffles. Is that what you’re suggesting?
I saw that explanation on another video but not sure if I understand it completely.
I have a chipper shredder that mostly runs wide open when it’s working and it seems much louder than the previous Craftsman chipper shredders I’ve had.

Plywood is a better choice not nearly as flammable as hay bales
@@100pyatt put a little re-bond carpet padding or horsehair carpet pad onto the plywood and that should make a very good noise insulator, just keep enough distance between the padding and anything hot. Leave the top open and raise the bottom just enough to get air circulation. You can get clean used carpet pad free from most any carpet shop as its recycled and they probably wouldn't mind if you pulled some from their recycle bin as long as you didn't leave a mess
Would make a great bon fire if spark's must to fly. I guess you could wet down the HAY!
@@dennis8445 Wet hay bales can spontaneously combust from time to time as they dry out.
Make your own muffler, just larger, use a 55 gallon drum lined with something. Might sound deeper. Most sound probably come from engine not exhaust. Put it in a doghouse or shed with exhaust outside shed.
I agree with the other poster, you get and A+ for the effort. That muff is thin sheetmetal, the exhaust "pop" flows into it and bang, like a drum. You could try a couple of old Cadillac muffs in series from a junkyard, I think they'd quiet the beast.

Don't forget to reduce the exhaust back down to 3/4
Like the saying goes,
"It takes a man to admit it"
and boy , you're the man.
Good informative video though.. thanks.
I am always amazed that so many people believe the problem with excessive generator noise is from the discharge of exhaust.
While improving exhaust muffler application will have some minor impact.
The vast amount of noise is being produced by the MECHANICAL ACTION INSIDE THE ENGINE.
The MOVEMENT and ACTIONS of the Valves, springs Rod(s) Crankshaft and Piston(s) DEVELOP the MAJORITY of the NOISES HEARD
The Engine case acts like a “bell” in amplifying and distributing these sounds OUTWARD FROM THE ENGINE AT GREAT VOLUME.
A better approach would be to construct or apply an insulated cover for the WHOLE UNIT with allowances made for operating temperature and exhaust gases.
But just throwing a muffler on it, is not the answer.
Thanks for watching and commenting. I enjoy trying to make things work better for us on our farm.
You need to shorten the lengths of Black Pipe! You want to have the muffler as close to the Engine as possible. You are getting nose from the Engine Resonating through that long length of black pipe, so by the time it gets to the muffler it's not really doing anything. You have the right idea, just need to make some minor adjustments.Also use a motorcycle muffler instead of a car muffler.
Thanks for watching and commenting. I’m wanting to try a golf cart muffler. Have a good one
You have to use dynamite to make it quieter, stick a few sticks under it and light them. Run like hell and then you'll see just how quiet it will get.
Das Boot thanks for watching
I always wondered if that would work. I guess now we know. Thank you for doing this video! **In the Army they had tactical quiet generators; it was basically just insulation surrounding all the generator with slots to allow for cooling/air...
Thanks for watching. I enjoy trying to make stuff work for me. Have a good one
I'd suspect a motorbike muffler would be better matched to this size engine, they also put rubber bungs in between the fins to deaden mechanical ringing noise on air cooled motorbikes.
dam, well thanks for testing my idea..i mean you beat me to the punch on trying that.
I did this a few years ago with a Duramax and I found that if I put a muffler on the intake as well and put the air filter at the beginning of the muffler on the intake as well as having the muffler on the exhaust it was quite a bit quieter around 55 DB
Thanks for watching and commenting. I still want to do a few more experiments on it. Have a good one
Thumbs up for trying 👍👍 Respect .
Hey pal. Stopped in to support and say hello. I met you in one of the streams I follow for sure.
When I first saw you putting that on I was like "WOW THATS A GREAT IDEA!!!!"... Part of me was a little bummed when it wasnt quieter. Very cool to try it though. Loved watching it. I was excited to see if it worked. hahaha
Thanks for sharing.
NYZ Outdoors thanks for stoping by our farm. I was hopping it would work. Sometimes we fail. But now I know. Thanks for watching 👍🏻
The exhaust is definitely quieter without a doubt. It's the engine itself that makes that noise. The intake also needs to be muffled
@@GerraldFarms You tried... i think it made a difference somewhat..... Next step is sound insulation panels for the sides
Pichardo Gabriel Thanks for watching. I plan to do more test. Have a good one

I was hoping it would work man definitely A for ingenuity and effort.
My advice would be to get rid of those exhaust leaks, might be quieter then
It’s also important to keep children safe when using generators so they don’t get electrocuted. Just reminding everyone.
Thumbs up for being honest. The average RUclips schmuck would have said it sounded like a Prius. Those motors are just loud. Thanks for the demo !
Thanks for watching and commenting. Being honest is the only way I know. I still want to try a few more experiments on it soon as I get time. We’re busy on the farm. Have a good one
The resonator in an exhaust is tuned to a specific engine speed to reduce volume at that frequency of exhaust pulses. Car exhausts usually have a variable resonator that opens up at high speed (pressure activated) that offers a second tuning for the higher frequency. The small engine is probably running at a lower RPM than the resonator is tuned for. I'd try using a scooter exhaust. I doubt if a motorcycle exhaust would have much effect, either, since they're usually tuned for higher RPM ranges.
You got quite the imagination.
thanks for watching
thanks for watching
That's a good thought but, the engine is connected to the generator at a 1-1 ratio. So the engine is set to run at 3600 rpm (which is around or above the resonate frequency of most mufflers) to provide the 60 HZ electrical output. My theory is that the 3/4" pipe connecting the muffler to the engine is too small, therefore keeping velocity too high. I think had he used the short run before the turn to put a larger diameter pipe (like 1-1/4 or 1-1/2) then reduced back to 3/4, would lower velocity and allow the pressure waves to react against one another. A lot of automobiles have this very thing (a resonator) usually behind or built into the Cat.

Build an intake muffler. Believe or not it works
bobelaviador thanks for watching. We’re going to do more experiments on it. Have a good one
Yes Intakte can also be pretty loud
The vast majority of sound on a conventional generator is from the engine internals and the actual genset on them.
That’s one of the reasons inverter generators are so quiet.
Helped my compressor engine.
Yes, the intake makes noise. Use this muffler for the intake. For exhaust, as soon as you can, increase the pipe to 1.5, then flex pipe to a glass pack muffler mounted with rubber hangers. Or just put a plywood cage around the generator (walls angled in just a bit)
I think you must have suppressed some of the exhaust noise, since you're able to hear more of the engine noise itself.
I did the same thing to one of my generators. Didnt make it a bit quieter. I think most of the sound actually comes from the generator rather than the motor considering gocarts have the same motor and arent nearly as loud.
That's interesting findings. I retrofitted the stock muffler from my Triumph Speed Triple motorcycle to work on a Generac generator with the same engine and it's much quiter than the factory muffler. Perhaps the automotive muffler is too high flow for effective sound deadening on this application.
That is kinda what I was thinking. I’m wanting to try a golf cart muffler when I get a chance. Thanks for watching and commenting. Have a good one
I honestly think it was louder with the car muffler.

DLK HAY sounds good I’ll have to try it. I’m thinking about getting me a generator for the pto on a tractor . Thanks for watching 👍🏻
they sure work good on the PTO. you'll have enough power to keep the lights on and work in the shop too.
Much of the noise you hear from those motors comes from the exhaust gasses impacting the exhaust pipe. The pipe leaving the motor is too restrictive. What if you opened up the area the exhaust goes into right at the cylinder head? Use a flange unto which a larger pipe can be welded to. Taper out from the exhaust flange so you can still bolt everything up. It still might be noisy bit give it a try.
Exactly what I said. I used to make my go carts louder by putting a straight pipe like that in it when I was a kid
thanks for watching.more test to come.have a good one
Is this Mr. Hand , from South Park. ?
Can assure you it works very well but learned the hard way about over insulating exhaust because had a huge build up of carbon in the cylinder & started running rough after long hours of operation ended up having to pull head off & clean piston & valves but other than that its the way to go.
Go to Home Depot and buy some sound deadning sheet (stryrofoam) and build a barrier around it.
Won't work. It needs air. Build something around it and it will over heat
I think we understand that part Lo-tech.
@@domesticatedwolverine4152 you said build something around it. Meaning you didn't understand it hahaha wasn't sure so I was informing you on it

You are a man of heart and soul. A valiant effort! Better luck on the next one. I might suggest an old motorcycle muffler that has a baffled inside.

That is one heck of a muffler job! AAA+ for effort! I tried using a car muffler on mine one time. I have the same exact generator except mine is called a “Sears Companion”. DeVILBISS made these for Sears. it did not make a huge difference, but it definitely helped. I wound up putting a factory muffler back on it but I am going to try to find a larger muffler that’s more appropriate for a generator.
Thanks for watching and commenting. Have a good one.
Hey, I hope you never got rid of this generator. Those brushless alternators are awesome! I know the engines are loud, but a car muffler, and some sound block paneling can help.
Thanks for watching and commenting. I still have it in my shop. I have not use it sense this video. The car muffler is still on it. I want to try a couple more mufflers on it.
The most important thing is vibration control. Right off the exhaust port I used a Stainless Steel exhaust flex pipe (with SS braid on the outside) to isolate the engine from the solidly mounted exhaust as any weak point between the two will fail quickly, as in the aluminum engines exhaust port/mount breaking apart.
archangel20031 Thanks for watching. Good idea. Have a good one
This is why Onan generators made for RV's are 4 pole generators. 4 pole generators only have to run at 1,800 RPM to have the necessary 60Hz frequency that we use in the United States. Lower RPM = less noise. The downside is that it takes an engine twice as big to produce the same power needed at 1,800 RPM instead of 3,600 RPM. I suppose if you had a belt driven 2-bearing 2-pole (3600 rpm) generator head, you could use a larger engine and run it at 1,800 RPM, but use a pulley on the engine that is half the size of the one in the generator. For example, a 6" pulley on the generator and a 3" pulley on the engine. That would turn the generator twice as fast as the engine. 1800 x 2 = 3600. The problem with doing that is that you might have problems with the engine getting too hot, since its air cooled and designed to be run at 3600 rpm under load. But that's just a possibility it may not be a problem. The bigger issue is that generators like the one in this video and most other portable geners, are a single bearing (on the rear) type and have to be directly connected to the engine VIA a "tapered" crankshaft in the engine. The generator uses the rear crankshaft bearing on the engine as its "front" bearing. Thus requiring you to rig up a v-belt pulley driven tapered shaft mounted on a pillow block to convert the generator to a belt driven unit. Lot of work and expense.. And then you still have a 3600 RPM generator, which won't last as long as a low speed generator will. My suggestion to anyone seeing this would be to just get an Onan RV generator. You can get them in gas, diesel and propane configurations in all kinds of sizes. Check Craigslist before ebay, people on ebay think those generators are worth 3 or 4 times what they're really worth.
Good try but the car muffler had little effect because it is not designed or "tuned" to the specific note produced by your generator motor. Mufflers employ some fairly exotic engineering in their construction to deaden and cancel the noise produced by car and truck engines. Remember what a fully unmuffled big old V8 before catalytic converters sounded like and how quiet those cars could be with the muffler intact (especially when they were new and the muffler not half rusted out). Best wishes!
Thanks for watching. I had always wondered if it would work. Now I’m going to do more experiments on it. Soon as I get time. Maybe a golf cart muffler. Or some mods to the car muffler.Happy 4th of July. Have a good one
