Product Details

The Factory 4.1 RCT incorporates the latest in FMF Resonance Chamber Technology™ both internally and externally. In addition, we achieve a shorter overall length that is less susceptible to crash damage and complementary to our 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 our exacting specifications and is manufactured 100% at our Southern California factory.

  • Available in Natural Aluminum Muffler with Carbon End Cap
  • Massive Power gains throughout the RPM range.
  • Huge weight savings
  • New RTS (Rapid Tuning System)
  • FMF uses the highest quality proprietary blend of alloy grade titanium made especially to our standards.

Slip-on. Replaces the stock muffler and bolts to the stock header or an FMF MegaBomb/PowerBomb header, sold separately. Header not included.

This is a 4-stroke exhaust. It is engineered for the 4-stroke engine architecture above and physically will not fit a 2-stroke bike. Verify your engine type before purchase.
