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 (the same engine found in Taotao, Roketa, Wolff, and many other Chinese scooters EXCLUDING ICEBEAR MADDOGS). To verify this will work, read the number on the bottom right side of your motor. It will read “QMB139” followed by other numbers. 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 re-jet the carburetor.
By the way, this is about a million times better than the cheap pipes you find on eBay.
