The Ultimate Motorized Bicycle Exhaust Guide - Best Exhaust 2019

In this video we take a look at several aftermarket motorized bicycle exhaust systems. We conduct tests looking at loudness, top speed, and acceleration. This video aims to give you a better understanding on how each exhaust and muffler will affect your ride.
The exhaust examined are as follows:

Brilliant sounds great like old 2 stroke dirt Bike iv got to build one of these

[@fujiwarafanboi6982]

I run a f2 thruster, good pipe, although build quality could be better, I had to clean it up. Although in its original form it works quite well, I suggest wrapping it in heat wrap though ( if your like me and wear shorts). If like to ride long distance wear ear pugs if you’d like to hear after a ride.

@@alexhickey5633 are them engine worth it? How fast can u get out of them

[@alexhickey5633]

@@ashleyhempstead9587 with the 2 stroke engines if you want to go fast. 70mph fast youre going to need a really solid frame and wheels. Port the engine like mad (vids on youtube on the zeda page showing that i believe) a bigger carb that is tuned. An expansion chamber from a dirtbike or mz65, be sure to get a genuine mz65 because the fake ones are shit. A smaller rear sprocket. Better cylinder head. Fred heads and jake heads are the best ones ive seen. Upgrade the cdi too if you can find a good one. The stock cdi isnt bad. Definitely get a better spark plug wire and sparkplug. An ngk b7hs is a good plug to start with. Last but not least, brakes. Put a good strong set of disk brakes on it. Dont go cheap when youre getting brakes

[@alexhickey5633]

And yes they are worth buying. Very easy to fix and maintain

[@Baldys_projects]

I like my banana pipe AFTER i modified it because its a very high RPM pipe stock, I added over 1' to the header and enlarged the stinger to 13mm because stock size was too restricted with a 10mm stinger so now its in the 60-63% range of the header I.D, with the extra header length and stinger enlargement the pipe kicks in way harder and sooner around 4,000 RPM's and pulls to about 8,500 RPM's with and rev's out to 9,500 RPM's . I also had the big Bertha pipe and the header was way too restricted so I cut a stock header off of a stock Muffler and welded it on the Big Bertha was a great top-end pipe because the Stinger was way too large on it and needed reduced to about 13mm as well to have more low-end, but it was a good pipe I liked it because it had my bike revving over 11,000 RPM!

[@vipervidsgamingplus5723]

How are you only maxing that engine at 29? I got thirty on a stock exhaust and without doing any tuning to the carb. Then upgraded to a expansion chamber and did thirty six miles per hour. Is the engine not running right? Is your fuel not mixed properly at the right ratio?

[@iJayBT]

@Bikeberrycom The test on 4:30, The lower left hand corner, which exhaust system was it? I like how it doesn't have much white smoke coming out and it seems like it's one of the top performer.

[@maistorcommentator1777]

Sorry for my english... In our country (Slovenia) people are tuning their 50cc mopeds and motorized bikes to achieve over 100kmh (62mph) from original 45kmh (28mph). One guy tuned his Tomos moped so much that he was able to achieve almost 150 kmh (or about 93 mph). He was driving his moped on a highway but this was an extreme example.

[@tyladube801]

[@bigfishfreak8714]

Im getting my F2 today how many teeth on the rear sprocket i have a 46 tooth will its still top out fast

[@bingus7361]

If you want higher top speed get a smaller sprocket like a 36 tooth and if you want more climbing power or more low end torque get a larger sprocket but you do sacrifice top speed for more acceleration. You could get a jackshaft too if you have a mountain bike I find them better because you get more gears and you don't have to worry all too much about chain alignment and sprocket adjustment

[@confusedwhatme]

I have the f2 thrust exhaust want to reduce the output the diameter of it 🤔 get a little more back pressure!

[@NewOklahoma]

My 80cc anbull motor I modified the stock took off cap and put straight pipe on it and the seal was broken on the engine to exhaust and the rpm was crazy high while bike was idling I took off from almost a dead stop and pop a wheelie almost a foot high it was hella torque and top speed it was unbelievable I was going around 40mph top speed and super fast acceleration I was amazed and I did on accident by the seal being broke cuz I fixed the seal it was totally different and slower after I fixed the seal

[@conniestevenson226]

The broken seal was allowing unmetered air into the motor that is also unfiltered. It was causing a lean air mixture to enter your combustion chamber thru the exhaust at the cylinder connection that was leaking.it will destroy your motor so dont run the motor like that.you probably did damage the motor already.thats why it runs different now as you say. Your air mixture is probably to rich to begin with tho

[@russbilzing5348]

I'm curious to know whether the bikes were properly re-jetted before the test or just slapped together and run in whatever shape they turned out in. Everything you change on one of these mouse motors affects the jetting in one way or another.

[@aeronmalaluanartsstudio4179]

Pls review bt80

[@adamdorris4081]

Ya know I don't really mind if I waste fuel. Got quite a few of those mufflers and just not right. I'm running a cut chamber and richened it up, Dio reed valve ported head oko setup from y'all. Several coils but running a stock one without a flywheel key so as to advance the timing just a little more. Base plate spacer, machined head for cooling and slightly higher comp, bottom end completely untouched besides the clutch components. Rolls 9500 rpms at 45mph. It'll go faster but I'm not trying to throw a rod. Stock rear sprocket, 1500 miles on it. 25:1 synthetic oil mix ever, 1 break in plug change, 2 clutches, 2 bucking bars, balls, and clutch covers, ordered a front sprocket from y'all never got it, 2 chains, 12 rear 27.5" tires. Bad on gas though. I'm surprised that that front sprocket hasn't let loose yet, the teeth are toothpicks... Might just order 10 so I can at least get 1 of them. I'm 250 lbs and growing.

[@SCUM-RACING]

best exhaust is a stihl exhaust bigger drilled PLUS 3 holes than 1 one hole or 4 or 5 holes but not too big 3 holes and 2 needs likes the originally size if you get high rev you want a good reving or ?

This video was fantastic until you included starting the engine in the test. It doesn't make sense to include pedaling and popping the clutch because none of that relates to the muffler. Just go 0-20 from idle and stopped, shooting for consistency with the power application. We're talking about differences of fractions of a second, don't include 5 seconds of human error at the beginning.

Most motors won't take off from a dead start with out heavy mods

The stock exhaust is not even made for a 2 stroke. If you have some fabrication skills get your hands on A. Graham Bell’s book: Two Stroke Performance Tuning.

Hello to all motorized bike riders all exhaust systems present or sold no matter who sells them. I can tell you that I myself tested each of these muffler you will just spend money for the look there is no performance to draw from that. I took the standard muffler and cut it in half to beat all the performance of its muffler sold on the net. That's going to change because this spring I'm going to sell real exhaust systems that will allow you to get 50% more torque and top speed then watch the sleeper ED site. this is where you will be able to order a real performance system as soon as possible.

scavenging is real atvantage of a tuned expansion chamber. the pulse of each firing and exh. event lends itself to pulling the fresh charge of pure air fuel into the cyl. . the pressure wave which otherwise does not get taken atvantage is used and in effevt acts like a turbo or supercharger increasing the volume of firing charge per event, meaning bigger bang.all chambers have different characteristics.
