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)
The FMF Racing Factory 4.1 RCT Titanium Muffler is engineered for high performance and durability, specifically designed for Honda CRF450X models from 2019 to 2022. Featuring advanced FMF Resonance Chamber Technology™, this exhaust system delivers massive power gains throughout the entire RPM range, enhancing acceleration and top-end performance. Its aerospace-grade titanium construction ensures both strength and lightweight performance, making it an ideal upgrade for serious riders seeking optimal power and reliability.
