If your mini dirt pit bike is having problems with the exhaust, then you don’t have to buy a whole new bike. The 2-Stroke Gas Motorized Mini Dirt Pit Bike Muffler with Expansion Chamber is easy to replace and will give your pit bike a new lease on life. Ready to be installed on delivery (with no additional aftermarket parts required), this muffler includes a silencer (very important if you don’t want to be deafened!) and built-in expansion chamber.
The expansion chamber helps the 2-stroke pit bike engine to increase the power output, which will, in turn, create a boost in speed. This muffler is suitable for installation on all Bikeberry 49cc Mini Dirt Bikes.
