FMF Racing 18-25 Yamaha YZ450F /YZ450FX 19-24 Anod TI Factory 4.1 RCT SO Muffler w/R. Carbon Cap

This FMF Racing Factory 4.1 RCT muffler is built from a proprietary blend of aerospace-grade titanium, featuring a blue anodized finish and a carbon fiber end cap. The Resonance Chamber Technology (RCT) is integrated both internally and externally, working to improve the exhaust note and overall performance. Its shorter overall length is designed to be less prone to damage from impacts and helps centralize mass by moving the muffler closer to the motor, which can make the bike feel more nimble.

Constructed entirely at FMF's Southern California factory, this muffler is made to their exacting specifications. The Rapid Tuning System (RTS) allows for adjustments to fine-tune the power delivery across the entire RPM range, offering massive power gains. This well-built component is designed to be a direct replacement for your stock muffler, making installation straightforward for riders looking to enhance their Yamaha's performance.

When installing this muffler, ensure you refer to the manufacturer's instructions for proper fitment and any specific hardware requirements. While this muffler is designed for significant power gains, it's always a good idea to check local regulations regarding exhaust noise levels and emissions for your specific area.
