FMF Factory 4.1 RCT Slip-On Exhaust for Honda CRF450X (2005-2016)

The FMF Factory 4.1 RCT Slip-On Exhaust for Honda CRF450X is engineered with the latest Resonance Chamber Technology to deliver superior sound and performance. This exhaust system features a patented core shape that reduces sound levels without sacrificing power, ensuring a quieter ride while maintaining optimal engine output. The patented canister shape increases internal volume, providing more space for sound-absorbing materials that enhance overall exhaust efficiency. Designed to improve exhaust pressure and flow, the chamber design results in a more refined throttle response and increased horsepower.
Constructed with factory-forward engineering principles, this slip-on is centrally balanced, making it more resistant to crash damage and easier to install. The system includes an innovative rear end cap that allows quick installation of tuning tip inserts or a spark arrestor, giving riders flexibility for different riding conditions. The FMF Factory 4.1 RCT is available in two configurations: a titanium version with a titanium canister and mid-pipe for maximum weight savings, and an aluminum version with an aluminum canister and stainless steel mid-pipe for durability.
With its carefully tuned core specifications tailored for each application, this exhaust system is designed to maximize performance on Honda CRF450X models from 2005 through 2016. Included components such as a spark arrestor and wash plug make it ready for diverse riding environments, whether for trail riding, racing, or recreational use.
