- The perfect length mini bike exhaust
Installed a seven-foot-long exhaust pipe on the Tillotson 212-powered Doodlebug minibike to see if the bike would gain any performance.
Tested the bike from zero to thirty and top speed.

Intro had me Rolling😂🤣..That was Awesome..Thinking outside the box..👍🏼🏆
This is the pinnacle of bored on a Saturday
Nah...he hasn't been forced to ask his wife about her day yet
Awesome April Fools joke! I was busting a gut on that first ride with the cannon. More please!
The comedy sketch was too funny, interesting that it got quicker from 0 to 30. Can you imagine a 7 foot intake? Just when you thought you've seen and heard everything 😂.
@11:03 when the exhaust fell off I started laughing haha
Keep up the entertaining videos❕🤙🏻
Very easy though to get too big of an exhaust pipe diameter on these single cylinder engines and kill the bottom end power.
Sounds great!
love the crazy mods. they may not work, they may not be cool, but its fun. and thats what im here for.
I wonder what the cars passing by are thinking about the long pipe 😂😂
There thinking what an awesome machine!!
This is awesome I never knew a longer pipe could add that much. I love the intro too u two😂
Sounds amazing nice, and Crisp. That's why I like that torque tube header.
This is what TH-cam is meant for! GREAT CONTENT ! 😂😂 nice comeback I can’t wait to start seeing people with 6 foot pipes 😂😂😂😂
Thanks!!
Now that was some high quality entertainment.
This is basically the most rediculous thing you have done...
I kinda love it
🤣🤣🤣Awesome video...you should go work for NASA!!! 👏👏🚀🚀
😂😂omg yes!!! Keep the exhaust just like that love it!!
The Japanese scooter dudes approve you just got to go up and add a cool tip 😅
Icing on the cake would've been the red flag tied to the end. 😂
Ironically this video is unironic. 😆
Japanese Bosozoku Style bikes and vehicles has been around for many years guess that had that knowledge because the pipe size they use are insane lengths 😅
Wow great minds think alike.
I feel like this videos gonna get a lot more views then usual
I don’t know about horse power, but it will move your torque range. That’s probably the effect your experiencing. I learned that years ago on my drag cars. Longer pipe moves the torque range up in the rpm and vis-à-vis short pipe lowers it.
But now I’m probably gonna go make a spiral 10 foot pipe just for shits and giggles on my new 225 Tilly 😂
don't forget the electric leaf blower blower😂
That part 2 tho got me like 👀
Wait a second,,, April fools day was last week.
Nice to see your twin brother in this. Lol.
Hi, would build something on a diesel engine
Shit man, rockets are next...
That's hella kool man!
Thanks!
I Freaking Love it!! 🙌🏽💪🏾
15-20 extra HP just in pipe 🤣🤣
Yes, and that's on the low side. Check out the 3-foot intake video! th-cam.com/video/x61JKb-A_84/w-d-xo.html
You got to be kidding me!
When are we getting that 7 foot intake
I'm waiting for the intake video ❤❤❤❤
👍
I can barely believe what I'm seeing ! But the expert did prove his point . What's next ?
Yes he did! 😀👍
when I was a kid I used my moms vacuum cleaner pip to make a up sweep for my cat minibike. she was not happy.and we use to run airplane fuel in it. fun fun fun.
I've heard that you should cut your header to the length of where the discoloration from heat ends.
POV: black 66 got the Saturday boredom
She's a beauty😂
point it up
So basically it did nothing, I feel stupider for watching.. Thanks man. Nice area where you live though.
4:35 what app are you using to test the 0-30?
Also when can we expect a intake video? 😂
I use a Dragy performance meter for 0 to 30. The intake video comes out this Wednesday the 12th at 4:00 PM
Now that's some hillbilly engineering there! Next will be the 5" exhaust tip
Gear it higher and you'll go faster lol. And I'm guessing that the long pipe is giving the engine a tad bit more back pressure.
Maybe... Be sure to check out the long intake video coming out today!
@Black66 You're peaking out your RPMs. You definitely can at least hit 60mph forsure. Maybe even higher. You got to 57 pretty quick and had plenty power left to achieve higher speed.
With my luck I would've gotten the massive horsepower boost, popped a wheelie and immediately destroyed all the exhaust rigging
Yes! lol
Imagine if the engine side of that pipe when it came off went into the tire
Lol, you're gonna need a red flag for that pipe so nobody runs into the back of it😂
Needs a big fart can on the end
Same thing happens running long tube headers on your car vs shortys.
What is the brake used? Im trying to find one for the axle hangers on the doodlebug
Check out the Doodlebug playlist. The first video shows the stretch and the brakes and other combos with this bike . th-cam.com/video/SuBNz0jH5pU/w-d-xo.html
That long pipe look's cool.I wouldn't want to behind you when you stop fast!,Literally would be a bad day for a couple of nuts behind you.
Hang one skateboard truck with wheels off the end of that pipe and you'll have a "Wheelstander" wheelie bar that will let the bike stand straight up, it will really impress the chicks, trust me...lol
My kpx I have on layAway is claiming 20 hp but now imhearing it's heavy so the templar x is faster I just want something I can throw a plate on an be legit
Try doing a loop de loop style
If it's for science it's not stupid!
Not gonna lie. I KEK'd a little bit.
I'm dying!!!
What app do you use to test your 0-30 and top speed for your runs?
I use digiHUD on the phone along with the camera GPS for top spped and a Dragy performance meter for 0 to 30
W H A T ? ... LOL 😆
what brand of chains do you use for your builds?
RLV Gold on Gold or RLV Gold on Black
I'll have to try those out. Thanks
Minda sounds like a mustang 5.0
🔥🔥🔥🔥🔥🔥👍👍👍👍👍👍👍👍👍👍😎😎
Can I fix a 8 foot on my lawnmower lol
Having a conversation with yourself Not Good You probably should seek help 🤣🤣🤣
1st
I love what you do ive always wanted to mess around like this with exhaust to see what it does what about smaller diameter pipe..
Thanks! Check out the Ram Air video coming out tomorrow.
did you try an expansion chamber yet?
I did try a pit bike exhaust on The Mega Moto 212 but no expansion chamber yet... th-cam.com/video/_UF3rb_4OBA/w-d-xo.html
