Featuring a custom flange and streamline design, the 66/80cc Bullet Train Muffler is a crucial component of your electric start engine. Unlike typical 2-stroke bike engines that are either 30mm or 40mm in size, the bullet train exhaust port is roughly around 35mm. As a result, most stock mufflers are not directly compatible which can create frustration in even the most adept motor bicycle enthusiast. The 66/80cc Bullet Train Muffler however has a compatible stud spacing and insert compatible with the Bullet Train.
This 66/80cc Exhaust Muffler is designed for use with Electric Start 2-stroke bicycle engine kits, like the 66/80cc Flying Horse Bullet Train Bicycle Engine Kit
Note: This part is not compatible with standard 66/80cc 2-stroke engine kits, such as the Mega Motors engine, non-electric start Flying Horse engines, Grubee engines, RAW Motors engines, and Power King (PK80) engines
