GY6 Big performance muffler: After market exhaust for 150cc 4-stroke Chinese scooters.

Select a language

"I have owned 5 different scooters over the years. 250cc CFMOTO, Roketa 150cc 4-stroke GY6, United Motors 50cc 2-stroke and a SunL 50cc 4-stroke QMB139. I can rest assured that no matter what make or model I have, Partsforscooters.com will always have the parts I need. I was impressed by your sales staff's knowledge of both stock and performance after-market parts. Shoot...I have a new performance muffler (169-3) for my Roketa 150cc that turned it from BLAH to YAH! Street Scooters, ATVs, Dirt Bikes, you name it and these guys have the parts. Keep rockin and rollin with your excellent service. You have a customer for life!"
Mike R.-California

"I am not a rich man, but I wanted my family to enjoy ATV riding. I bought three different Chinese made ATVs; a 250cc for me, 110cc for my wife and a 110cc for my son. Lots of people said beware, because you can't get parts for them. But, I found you guys online and all 3 of my orders shipped quickly. Beware of nothing, because Partsforscooters.com makes it easy and obtainable on my budget." Jeff A.
