The Factory 4.1 RCT for KTM and Husqvarna 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.
-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.
