Factory 4.1 RCT Slip-On Muffler.

The Factory 4.1 RCT incorporates FMF´s Resonance Chamber Technology™ both internally and externally.

In addition, FMF achieves a shorter overall length that is less susceptible to crash damage and complementary to their Factory Forward Engineering - moving the muffler closer to the motor to centralize mass.

The Factory 4.1 RCT is constructed from only aerospace grade materials that meet their exacting specifications and is manufactured 100% at their Southern California factory.

Massive Power gains throughout the RPM range.

Huge weight savings.

RTS (Rapid Tuning System).
