Chinese scooter performance scooter exhaust
This performance exhaust pipe is what you need if you are looking for a little bit more power and sound out our your 50cc scooter. This exhaust works great with big bore kits! This will fit all qmb139 engines. (this is the same engine found in Taotao, Roketa, wolf, and many other Chinese scooters) to verify this will work, read the number in the bottom right side of your motor. It will read “qmb139” followed by other number. This pipe will give you a snappier throttle and a much more free flowing exhaust. Pair this with a performance pod style air filter for max results. You will need to rejet the carburetor.
By the way this is about a million times better than the cheap eBay pipes you find on eBay.
