The Ultimate Motorized Bicycle Exhaust Guide - Best Exhaust 2019 

I was kinda hoping to see a demo of each muffler's sound, as well. Not just the volume ratings

I dreamed I was a muffler. I woke up EXHAUSTED! ;) ;)

Just installed my F2 MAN BRO.. LOOKS AMAZING... CANT WAIT TO HEAR IT. AFTER SURGERY..

I dig the street straight pipe. It's pretty quiet and reasonable 20mph in 8 seconds really isn't bad to glide through the neighborhood without turning every head you see.

That's an awesome bicycle!

I watched this then purchased the F2 ...! Not only did it increase speed and power, the exhaust system is a attractive looking system on my bike.....!

Trying to watch this this bad wifi almost made me throw my phone and leave a nasty comment but i've calm'd down and now appreciate the video and good information. People on the internet forums said the cheap expasion chamber sucks but this proves otherwise. A great upgrade for 30 bucks

BikeBerry, you guys rock! I get most of my parts and accessories from them...My latest was my 3-spoke Mag wheels which are still performing perfectly! Thanks, BBR!

Very helpful thanks

Awesome video well done and informative. Cheers

Love it guys thanks

Thx your expérience..very very thx..

Nice video btw guys💯💯💯💯🔥

I really would've liked to hear a sound comparison between the different exhausts. That would've been more useful for selecting my new exhaust... I ended up ordering the Voodoo

this was a very helpful video

Great video

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

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.

I’ve got the thrust exhaust and it is soooooo loud! I love it

Excelente 🇩🇴🌎

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!

Nice work now I have a idea what I want to buy from you guys

I bought your red clutch pads.... don't need to use them now..but I got them🙂

I just drilled holes in my stock exhaust. Got loads more low end grunt and about 3 mph on the high end

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.

The f2 thruster is nearly impossible to tighten on the magneto side the pipe blocks the bolt from getting the Allen key in

great vid

That’s why I run the f2

F2 THRUST REMINDS ME OF A SUZUKI TC 90 EXHAUST AND THATS WHAT IMA BUY Just in black

That's why I run the f2 pipe it sounds like a jet but tork and speed will get u their and hills are no competition

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

I have a Performance Speed Demon exhaust with an expansion chamber and muffler from my 49cc on my 80cc upgrade. It worked wonders on my smaller motor and can't wait to see how it performs on this one. Still got a few more things to do to my new motor before I can take her out for her first start-up. Hopefully I can upload her first start video.

I'd like to have a quiet bike, it sucks that I have to give up so much power, honestly the stock exhaust is loud still for me.

@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.

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.

Huh cool man

Do you guys know if the BBR Tuning High Performance F2 is good also for 100cc s mothor for bikes?

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

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?

Is there a performance pipe for peak performance, but also more quiet for cop avoidance?

How about you guys show someone how to assemble the motorized mag wheels on a motorized bike

hell I got 80cc with cnc head and reed valve mani with stock exhaust with the cap revoved on a occ stingray hitting 43mph with me at 173 pounds

I have the same ring but idk hot to install the chain in this wheel pls can you explain me broo

Do you have this guide in the 4 stroke 80cc predator engine

Where can I buy the BBR performance f2 thrust or the flex fit poo poo exhaust pipe! thanks

@Whoop!

What about the expansion chamber with muffler? How loud is it?

Pls review bt80

Does VF two thruster exhaust have a muffler in it

Dude, you're not supposed to follow him with the speedometer, you're supposed to let him pass you, you'll screw up your results 🤦‍♀️

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.

ehhhh idk abt this also it matters what engine you have as well keep that in mind

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

Do the ultimate bike build for power, carb exhaust etc.

i did the stupid thing to use an scooter tuned pipe on my motorized bicycle god.... the sound looks awesome and i think it goes 30% stronger than before... but now i do need a proper carb and reed valves to make this uses all this power due.... since thats bigger than these exhausts.... i think the engine doenst fill right lmao

what engine size did you guys used? 49cc or 80cc?

Has bikeberry ever put out a decently produced video...

Most aftermarket pipes will have some rust of difference, whether it be on high end or low end!

F2 muffler you have to heat wrap it. If not it melts polyester pants

CAN WE GET A PARTS LIST FOR THAT BIKE

Yo is the EG hatch at 3:21 for sale?

thanks heaps

Get a mz65 or a zeda 88 exhaust then you'll know what power is..

My sprocket is off centered cuz my large 2 in hub and i drilled a few holes in exhaust and on a warm engine i can hit 40 to 50 with alloy rims 29in

What is other upgrade for bt80?

Do yous deliver to ireland

what kind of oil do you use

i need more Torque for pulling hills what would you Recommend

I got the f2 thruster in mine also called the thrust racing muffler 😍😋! Check mine out plz!

I put a f2 on my bike

My bigger carb don’t work on mine maybe because I can’t fit the better Exaust pipe on

What about the mz65 ?

Why does everyone of these engines have the metal on metal clinking sounds to em.i just put on another gasket to try to stop it gna wait a couple more hrs to test it but I dnt want to lose performance 🤔

I do 42mph on my 66/80cc china girl stock engine with stock muffler. No silencer tube but maintained the bottom cap. Stock speed carb with no air filter. 40 tooth sprocket and a mini spark plug model L7T.

I AM IN LOVE WITH THE F2 THRUST BUT CANT AFFORD IT BECAUSE SHIPPING TO MY COUNTRY IS LIKE 150$

lmao why the hell would you want your bike to be qUiEt when you have neighbors to piss off at 2AM

The worst part about aftermarket mufflers is finding the control arm bearing. Once you figure that out it's all uphill from there. 😆

The mz 66 pipe is still the best

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. In this book you will find everything you need to know in order to build a pipe , to fit your engine, like a glove. Built my own for my style of riding and is perfect.

Hi I have a question, I would love to buy an exhaust from you guys, but is it possible to send to the Netherlands?

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.

I would want the quietest so I can slide in under the radar

The song?

I looking for to do 60 mph ....can you help me out what I need to get to top speed 60mph

Top speed 29 mph? I can do that with a modified stock exhaust. Are you testing with 50cc engines? My builds run between 35-50 mph, whatever the customer wants. Bikes by Bill.

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. Sleeper ED

Why un u vídeo the top speed is 29 Mph and the same motor in Puerto Rico the top speed is more 40 Mph i don't understand why

Why did you put music over the sound of the pipes?

I believe that starting the motor, and then going to the starting line, followed by accelerating without any pedals whatsoever would have been more consistent.

For us that no what really works for power an it's sure not these

A heat shield would be a nice humane touch. If you ever see a hot bike laying on top of the rider you can hear the flesh sizzling.

Did I miss the weights of each system installed?

Hello, please add Russian subtitles) we just don't have such videos)

My bike runs 37 mph. All stock

Where I can order me them ...I'm looking to get me one pls send me the information thank you

I'm sure I know the answer, but which is best for climbing hills, is it the F2

why do you sell rubber motor mounts but never use them! i feel no vibration at all on bike! at first i didnt have them tight enough and it was terrible but after tightening them tight as gerbels ass there fine!

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.

Please look up cosine error. You are not using the speed gun correctly. Otherwise this is really good information.

what is this?
