Mufflers

Decades of racing development went into the design of the FMF Powercore 4 to improve the power and performance of your dirt bike or ATV at a practical price.
The FMF Powercore 4 is a muffler that will boost power and torque throughout the power range, making the Powercore 4 usable for all types of riding.
FMF designed a Hi-Flo end cap and core for the Powercore 4 to increase power by creating a free flowing end cap and a core that allows room for exhaust pulse. This results in a consistent power curve.
The FMF Powercore 4 uses and advanced cross-weave packing that is more durable then the traditional packing.

The cross-weave packing also keeps the Powercore 4 at a reasonable sound level by dissipating the exhaust sound. FMF constructed the Powercore 4 using aluminum to keep the weight down with stainless steel components for extended durability. The FMF Powercore 4 includes a USFS approved spark arrestor. Fits: HONDA CRF250R 04-05, CRF250X 04-12
