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 slip-on exhaust delivers unmatched performance with advanced FMF Resonance Chamber Technology™ that enhances power output across the entire RPM range. Crafted from aerospace-grade titanium, this exhaust system offers exceptional strength and durability while reducing weight for optimal handling. Its shorter length design minimizes the risk of crash damage and aligns with Factory Forward Engineering principles by positioning the muffler closer to the engine for better mass centralization. The vibrant blue anodized finish and carbon fiber end cap give a sleek, aggressive look that complements the bike’s aesthetic. This system is engineered to maximize airflow efficiency and boost horsepower, making it a significant upgrade for serious Kawasaki KX450F riders seeking top-tier performance.
