FMF Powercore 4 Exhaust 044156

The FMF Powercore 4 exhaust system delivers measurable horsepower and torque gains through computer-optimized design and dyno-testing, engineered specifically for 4-stroke engines where every cubic centimeter of flow matters. The hi-flo end cap and round perforated inner cores reduce backpressure while the stainless steel mid-pipe and lightweight aluminum can keep rotational mass to a minimum. Whether you're chasing lap times or maximizing trail performance, this system provides the exhaust evacuation efficiency that translates directly to usable power without compromise.
