- The Factory 4.1 RCT is constructed from only aerospace grade materials that meet FMF's exacting specifications. RCT (Resonance Chamber Technology) features a patented core shape that lowers decibels while maintaining maximum power output. FMF's Factory Forward Engineering centralizes mass and is less prone to crash damage. Internal ducts in the chambers of the RCT system increase internal volume for improved exhaust flow, resulting in power gains throughout the entire range of power. The innovative end cap features simple installation of the optional tuning tip inserts or included spark arrestor with the removal of four screws.
