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 Blue Anodized Titanium 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 specifically to our standards.
