- SIMPLE Exhaust DIY for Go kart/Minibike!! (Under 10$) [4K] Its a custom header with a built in muffler that would work for any Predator 212cc, 420cc, 79cc, 131cc engine. Also any Honda 163cc/196cc Engines. Motorized bicycle 66cc.
Lawn mowers. Briggs and stratton engines.Pit Bikes. Mini Bikes
You name it.
If you are new, Subscribe to the channel and hit the bell; I post awesome projects from 2 stroke minibikes, off-road dune buggies, go karts and much more!!
🔴Thanks for watching!!🔴
**You will obviously be able to alter the length and thickness of the pipe, buy additional pipes. Or not make a muffler like I did. You cant do without a Welder or a Grinder.
***Tractor Supply sells thread in mufflers, you can also find them on ebay.
****The rainbow effect only works on thin steel that is heated up to 600 degrees.
I am only a beginner at welding, I could have done so much more. Feel free to give me tips on my welding.
Depending on the application, this exact should provide a better sound, and more air flow. Leading to more torque and HP.
I Used:
1/2 90-degree pipe
1 1/2 inch pipe
2 washers

Purchased this to replace a guide pulley ruclips.net/user/postUgkxO9seYZjlnuP5UvMkb7osQW3WxPVeSnPk on our John Deere x304 snowblower. As I stated in the title, it is just about perfect. The stock pulley has a spacer at the bottom. I used four washers to emulate said spacer, and it works perfectly now. Great product, and great price especially if compared to typical JD prices.
Don't know why anyone wold give you a thumbs down. You gotta start someplace and you will get better and better.
Maybe the voice that did it for me
It was the improper protection from the welding gun that did it for me
dunno if anyone gives a damn but if you're stoned like me atm then you can watch all the latest series on InstaFlixxer. Have been binge watching with my gf for the last weeks =)
@Dakari Lionel yea, been using InstaFlixxer for months myself :D
@Dakari Lionel definitely, been watching on InstaFlixxer for since november myself :)
You did a nice job young man. You need to weld a bracket from muffler down to a location on engine so muffler weight dont crack your pipe...
Sound advice i didn't even think of that 🤔
Someone get this kid a work bench ...
Our garage has no space for a work bench. But i do have one outside
Haha yeah, well then someone give this kid a big, complete workshop.
Some suggestions for you, run what you call header all the way through larger pipe (small pipe thru large), drill bunch of holes in inner small pipe, within large pipe only, fill outside of small pipe with steel wool...will give it real nice sound and flow better than what you did. What you did was create a chamber that has exhaust gases pulsating within larger chamber disturbing exhaust flow (translation hurting engine performance)
Its similar to a 2 stroke expansion chamber. Ive come to understand that you dont want that on a 4 stroke
The welds may look sloppy to some, but its a work of art to me!
Haha Thank you!! its what a 16 year olds art look like
@@VasilyBuilds i think the sloppy welds make it look cooler it makes it look like your own instead of a after market part
Agreed, looks better than most welds that come from the factory in China. True story....
You need a helmet so you can use both hands and be steadier. And gloves, the arc burn can be significant on longer welds. But not too thick for gloves, you need the dexterity.
Chops to building it yourself, keep it up. You'll only get better and better each time. How are you doing 5 years later now that I check out the original date?
Great skills, kid !!!
Wear gloves while welding
Will do. Better than getting burnt
Bram van wieren and sleeves at least and possibly a wearable helmet
ben garcia Yes, you will want to protect your skin from flash burn because the welding is worse than the Sun and you don't want to get cancer. Don't ask me how I know...
My grandpa had gloves but the arc-welder rod burnt through his glove and hand to the bone but it offered a lot of protection. Wear ya gloves kiddos.
Welders complaining about burns is like a baker complaining about to much flour on their clothes
Its gonna happen
Good job, sounds mean! Just one tip.. Turn up the amperage on your welder a little bit and the welds will be much smoother : )
sentradynamics the welder is juttery by nature. Very weak motor. It is going to burn through if I turn the amps up. Just ran a too fast wire speed
That’s awesome! It sounds great!
You're welding galvanized steel, very dangerous without proper air movement
Yeah it'll make ya sick
He was under a carport.
How much airflow you need.
@@robspear03 my welding instructor said he welded some in his garage and couldnt go to work for as few days cause he was so sick. you act like poisonous gas is no big deal
He better be careful, I heard welding galvy s
Will make you shit your pants😂🤣😂🤣😉
walt krindlpleth lol
I like welders neighbor
thanks for the tip
Bright brown individual for doing all this at home by yourself! Good job
Looks good
good vid but i have a quick TIP for you guys that do this. knock out that inner piece of exhaust pipe thats left over after grinding. it gives you maximum exhaust flow. the piece can be seen at 2:03
Yes It is better to knock out inner piece
Sounds badass
It's good to see how much your welding has improved, and it is good for someone (me) just getting into welding to see that nobody starts perfect.
Yessir!
“Use a welders neighbor” lol funny as hell the face you put after you caught yourself.. I haven’t seen this vid. Keep up the good work!!!!!!
May be sloppy but I fuckin love the attitude and the way you approached it, good shit man
That's actually pretty damn cool looking man.
Good job man! Keep at it!
Great job! 👍👍👍
Sick
Cool
Nice ideas and skills!
Amazing video bro !!!!!
other then the welding needing some clean up as in grinding your welds smooth for an overall clean look! the sound is spot on to a muffler! i give two grade's for this type of work function & quality i give you an A+ for the overall project & goal of the function! as to the sound of the pipe & keeping the performance of the engine its self! =) & as for the welding... a B- you could have made a better quality look by grinding the weld's smooth to give a much not only cleaner but much more smoother look! & thats what sells for bucks all day long $$$$$ love your video's man keep up the good work. spikeman out!
You have Come a long Way!
Great job bro
One wheel peel FTW
Wow 😮 nice silencieux d'échappement bravo good job
Thank you!
I love your videos , can I ask why you put a restriction on it after the first video, and did it help more with or without the restrictions, I was gunna make a strate/ dump pipe for my one wheel peeler
Yes! I will put one on my ariens snow thrower and cub cadet riding mower. maybe one on the leaf blower. 6hp. I am looking inti fabricating gunmetal heat shiels like the kind seen on military rifles. hmm?
Nice work mate. I'll be making one for the new kart i got. Waiting on a new motor to turn up. I made one for the small off roader. Full stainless.
Thanks!! welds weren't there tho. You have some hella nice projects!! Maybe one day I can make me an offroader like yours
Vasily Custom Builds Thanks mate. Got my motor and parts just now. By the end of the weekend we should be in business.
I have got a bit on the go but enjoy working on them.
And yes it would be good for you to make an off roader. Keep at it mate . They aren't hard to build.
Cheers bud.👍
I'm gonna try and do this tmw the only they I would recommend is putting some type of screen over it bc most of these engines run a bit better with some restriction
Thank you thank you thank you thank you
You are going to need a bracket
The N.V.H. will soon crack the Flange weld .
Just a throut from a Kart racer / builder
Yes I rammed a mailbox and it broke. I since have built a better one.
You can unbolt and rotate the pull cord cover to the rear of the cart.
Your welds have come a long way!!!
Good work man👍 for everyones info a straight pipe with no exhaust sounds like absolute dooky and backfires sparks. Definitely gotta have an muffler/resonator
He is so smart
Will going from a 3/4” stock exhaust to a 1/2” exhaust damage the engine due to more back pressure?
Inner diameter? Yes It will overheat and make less power
Yes you do have sloppy welds, but you are not the only one. Great job on the custom muffler! Im thinking about building a custom glasspack for my 3 wheeler that has a Briggs 5hp. Any tips or tricks?
Thanks man I was a n00b at welding back then, now I somewhat am better. But I would suggest using a lower setting on welder and making sure pipes have a good fit :)
What was your voltage...or whatever that you had your welder set to?
I used a cheap flux core setup (no shielding gas) I used setting A and B and a slow wire speed
A question: can i start my honda engine without muffler because of loudness. My 2 stroke bike without muffler is loud as hell
No, the muffler is low pressure area that creates vacuum and pull the heat away from the heads/valves. As in the video, he did not create restiction ,the larger tube is a low pressure area that creates flow. An engine is a pump. The expression of "back pressure " is not correct, it is just something people said to explain why a engine did not run well with out an header or exhaust pipe. He did it perfectly, but it is not a restiction, as he said in video. The chamber he created is larger area ,the goes right back to the the smaller pipe. This is low pressure area that causes the exhaust gas to shoot out. Vacuum flow, not back pressure or restiction. Also going with too big a exhaust pipe will delete this effect. It would have been better if he had drilled out inside diameter of wash to match the size exhaust pipe going into and out of chamber. If you look at 4 in 1 header the transitions to muffler are smooth and funneled for flow.
Just got a welder..... Welding a shopping cart to a long drift trike frame I'm making that will hold 4 predator engines with torque converters... Will add train horn with air compressor and wd40 pump for exhaust fire (pipe will be shaped like megaphone to be extra annoying to neighbors
Make it epic! And document it
@@VasilyBuilds hell yeah man! Gonna get my friend to drift it while I chase it with my homemade fpv racing drone
I wanna see that
@@habdman lol ill try to remember to let you know when i upload it
If you straight pipe it, it will pop and shoot flames naturally
What is the sound difference compared to stock exhaust? Obviously its gonna be louder but is it much louder than stock or what? I don't want to annoy my neighbors too much
You have come a long way, 2020 weld's look much better.
Whoever disliked simply can’t do no good in life great video 🤙🏽
Wear gloves and use both hands on the torch. I like to use my left hand up by the nozzle to steady it and my right to pull the trigger and control it. You'll get much better welds. Dont weld galvanized without ventalation. Remember:A grinder and some paint will make you the welder you ain't. But still try for good welds bad welds crack and break and it could be a really bad day for someone
zenith0000 You're 100% right. I started using my left hand near the torch to steady. Will install a fan of some sort for protection against the smoke.Thanksdvice!
Vasily Custom Builds just dont point the fan directly at the weld. Have it suck away or else youll blow all your shielding gas away from the weld and it will be weak
zenith0000 I probably would've never thought of that in a 100 years lol . Thanks
Vasily Custom Builds anytime been screwing with harbor frieght welders for a few year. If you look on my channel you can see a custom drag rail frame i welded up
i know this is late but i noticed you said not to blow the fan twords weld due to shielding gas being blown away, but i dont think hes using shielding gas it sparks and acts like flux cored also he has no tip installed so even if he was using shielding gas it isn't providing the correct coverage.
What kind of Life axle you have I have the same go-kart and same setup but it's only a one wheel
Can u still use the stock filter to add a exhaust??
Damn, I wish i could buy one, I never tried welding, and I am too scared too, even though my father suggested too, most exhaust are expensive nowadays, but I honestly think yours would be an awesome addition to my off-road go-kart..
Honestly at the time of making this video I did not know anything about welding. I only watched my dad. But it turned out pretty great. now I am pretty decent at it. It's never too late or early to start welding I recommend it. You can start with 100$ harbor freight welder. And yes exhaust are expensive, I am thinking about doing a giveaway some day :) Thanks for Watching!
get the 125 flux core from harbor freight works great
Sean's Garage
Thanks! I'll try it out, you can't go wrong with Harbor Freight! :)
Edit: My grandpa already owns a welder, but thanks though! :)
Yeah, only issue is it uses flux not gas so u have to clean the welds more but you'll get used to it
Sean's Garage
Alright, I'll consider it a starter welder if I really like welding. :)
Aside from the not wearing gloves part, not a bad job. The welds themselves aren't neat by any means but the idea and ingenuity is pretty badass. I like the idea mang.
Thanks. Yea looking back I see a lot of flaws..
Vasily Custom Builds I need to find a welder's neighbor still 🙂
i know you have improved alot since this video. but you really gave ppe the finger on this one
Can you please tell me where I can get some of that smaller pipe I want to do this but can’t find 1 inch pipe anywhere. Or just let me know what size the smaller is. Is it 1 1/2 inches or half inch. You said inch and a half but on screen it said half inch. Confused. Thanks
Ideally you want to use 1" OD tubing. You can get it from tractor supply or ace hardware. You can also use bike handlebars
Needs a bracket, will crack soon
Turbo Garage I re-did it with some better weld. Its still there..
Vasily Custom Builds It will eventually crack the head.
@@lakejonggg Doubtful.
Its a light stinger, not anything heavy about it. I wager it weighs no more than stock.
What thickness of steel for the 1/2" pipe? 1/16th? 1/8th?
That "gasket surface piece" has a name. It's called a flange. ;)
wear a long sleeve shirt prevent sun burn from the welder
riley james I agree. I got really bad burn from not wearing long sleeves. I wore an apron, but not long sleeves.
The gadget surface piece is called a flange :3
Quick Question. That gasket surface piece you took of the old exhaust and grinded down. If i don't have one of those do you think i could just make me one out of a thick piece of metal? Or does it have a special purpose that a normal piece of metal doesn't have? Thank you
you can make one out of pretty thin steel. no less than 1/8. It will warp and flex and cause a bad seel. The thicker the flange you can cut the better. It does not have any specific purposes.
Vasily Custom Builds that is awesome and helps alot Tank You! I actually still have the seeling part between flange and cylinder. So now I just have to make the flange out of thick steel. :)
Not all grinders are good welders, but all welders are good grinders.
tip before you weld smooth everything down so you have a nice clean bear piece of metal to weld to so that the welds stick to the metal you want to weld
Which muffler would you recommend to buy online for the predator engine
rlv muffler
Are there any mufflers to buy online that fit into hondas engine?
Love this comment section
What kind of pipe is he using and where can I get it?
Does it hurt my engine if I ride without the exhaust system ?
If you ride for long-term, than yes it will. It will loose horsepower over time as the exhuast valve gets warped by the wind.
Wear gloves when your welding and use 2 hands when your welding it gives more stability and controlled movement
does this work with a 161cc?
All 4 stroke engines must never obstructed for full potential.
Nice build bro where you from?
live in Tennessee, from cali
0:6 lit
So does it make the engine louder?
It will being that it's not a muffler. This is the equivalent of straight piping a car.
Did it break off yet? Wear gloves and sleeves when you weld.
you know?
the vibration.
it will cause crack at the weld.
You should make more vids of your go kart
I went to McDonald's in it
Seems to sound loud to me and I want to make mine as quiet as I can
You need to brace your header or it will undoubtedly break into right at the weld.
Are you using a 210 mig welder or a Harbor Freight 125 flux core welder? This is most important 2nd what gauge pipe are you using this is also important if you want a cleaner look without grinding your weld away. Here is a tip on making a mini bike exhaust and I recommend 1” pipe to start expanding to 1.75” remember you want power your header needs to breathe 1” minimum to start if you’re running real thin gauge pipe and using a mig 210v or a flux core 110v run low use .030 wire set speed on 5-6 once you puddle move around pipe in a tight circular back and forth remember thin pipe set on low wire speed 5-6 as soon as melt starts start around should give decent weld without burning through pipe that eliminates excess grinding won’t look good. Only use grinder to clean up spatter or spray your moms cooking spray and spatter will come off easy with wire brush. That’s all I can tell you without the specific’s on welder wire and pipe gauge!
not important ,im 58 welded 35 years I built a 25 foot black iron shrimp boat using h.f. welder i have built 20 gal pressure vessel a.s.m.e.open but weld
Should put steel wool inside it makes it quit
I want to straight pipe mine just to make it shoot flames.
Where did you get your pipes from?
They are galvanized pipes from tractor supply and home Depot
Didn’t know Han worked on go karts
better than before?
Bud, the peice you had was called a flange
What about the rd bike
Don’t miss out on more mini bike shenanigans and fun! Facebook group MINI BIKES AND CHILL
facebook.com/groups/1456529424737006/
it is called bluing (color blue)
how does exaust help?
Mostly just for looks...
Also helps with torque and higher range power.
Puts back pressure in the head causing an increase of HP. Too much and you'll grenade the motor
Why did you get rid of this Exhaust
I let my sister ride my go kart and she flipped it on the grass and my exhaust broke off.
I would bend the pipe more
How many hp has that engine ? 7?
yes
Sorry, that exhaust is way too restrictive. Exhaust header pipe for a 212 should have an ID of 1" minimum. The flange that comes attached to the muffler is both too small, and too thin to support a header. Best bet is to use 1-1/8" washers doubled up for a 5/16" thick flange minimum.
Can you please give me some more detail on how to do this ...I have a welder and want to learn on my predator 212 trailmaster project ...also be happy to check out some educational links if you have any ...I'd be much happier to make something myself and would luv to learn about how's and why of size/restrictions ...I have adhd really bad forgive me for so long
My neighbor won’t let me use his welder what do I do 😂
You will need some bracing or in time the welds will crack due to vibration.
First off...wear gloves when welding. Second, never weld on concrete. You got a lot to learn Ol' Son.😂
Haha. Yea you're right. Is it because concrete explodes?
Vasily Builds It can but you’d have to get it real hot say you where welding a foot on flat steel if your elevated it’s less likely but my welding instructors told me it can blow a basketball size crator and be deadly
Don't restrict exhaust on 4 stroke motors. That just restricts power.
Restriction is for 2-strokes.
see heres what ya didn't do ....put a preforated pipe between the washers and fill that larger tube with steel wool making a modified glass pack exhaust
