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 exhaust system is engineered to deliver exceptional performance for KTM 500XCF-W and FE501 models from 2020 to 2022. Incorporating advanced FMF Resonance Chamber Technology™, this exhaust enhances power output throughout the entire RPM range, providing significant gains in acceleration and top-end performance. Crafted from aerospace-grade titanium, the muffler features a striking blue anodized finish with a carbon end cap, combining durability with a sleek aesthetic. The design includes a shorter overall length for improved crash resistance and better compatibility with Factory Forward Engineering, which moves the muffler closer to the engine to centralize mass and improve handling.
