For the price this was perfect. Fits nice on my af27 dio you will need to remove or shave the plastic trim piece. Sounds nice all in all great value Read more

Great product for price would buy again Read more

A little cutting and re-welding I fit it on my motorized bicycle. It’s awesome I highly recommend it. Amazing quality. You will have to do some port work and a larger carburetor/and up jetting to get the full effect on a 2 stroke motorized bicycle engine. Read more

I had to do a little modification to mine but that’s because of my OCD. But honestly even without the modification I did, this exhaust still is a great product. Read more

Cut it right at the welds so that it was thicker material. Re welded it back together to work on my gas bike. It’s fire!! Cheapest option Read more

This is definitely a good upgrade!! As you see in the photos the difference between the stock pipe and huge expansion chambe,how much of an increase in power you'll get,even from a small 50cc 2 stroke engine! This is definitely worth the price! This pipe has a completely detached exhaust flange pipe connector, meaning you can litterly take any flange and pipe, and connect it to the expansion chamber, allowing it to be used with almost any engine! A definite plus for any looking to gain gas mileage and/or power, or both!! I would definitely recommend this exhaust pipe to anyone with a smaller 2 stroke engine!! Read more

Great pipe for motorized bike kit, pipe came clear coated and had surface rust under clear coat, magnet also sticks to pipe. With some modifications it fits just about any frame, is pretty quiet with muffler. I was able to buff pipe to a pretty nice finish also. Great buy for the price. There are some restrictions with the way it was assembled before I cut it up, so if you are using it for a moped keep that in mind. Read more
