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.

  • Highest-quality proprietary blend of alloy grade titanium
  • Blue anodized titanium muffler with carbon end cap
  • Massive power gains throughout the RPM range
  • Rapid Tuning System (RTS)
