FMF Racing Honda CRF450X / RX 21-24 SS Alum Factory 4.1 RCT SO Muffler w/ R. Carbon Cap

If you're looking to get the most out of your 2021-2023 Honda CRF450R or CRF450RX, especially when pushing it on the track or trail, upgrading your exhaust system is a key step. This FMF Racing Factory 4.1 RCT muffler is designed to give your bike a significant boost in performance and durability.

FMF has incorporated their latest Resonance Chamber Technology, both inside and outside the muffler, to help improve power delivery across the entire RPM range. The design also makes the muffler shorter, which not only helps centralize mass by moving it closer to the motor for better handling but also makes it less likely to get damaged in a crash. This muffler is constructed from a proprietary blend of aerospace-grade titanium, known for its strength and light weight, and features a blue anodized finish with a carbon fiber end cap for a factory look. It's built entirely at FMF's Southern California factory to their exact specifications.

This muffler is designed as a direct replacement for your stock unit, making installation straightforward. You'll notice a substantial increase in power throughout the rev range, making your bike feel more responsive and potent. The Rapid Tuning System (RTS) is also a notable feature, allowing for easier tuning adjustments.
