FMF Factory 4.1 RCT Slip-On Exhaust for Yamaha YZ450F and YZ450FX - Titanium and Aluminum Options

The FMF Factory 4.1 RCT Slip-On Exhaust is engineered to maximize performance and durability for your Yamaha YZ450F and YZ450FX models from 2014 to 2018. Featuring all-new Resonance Chamber Technology, this exhaust system is designed to optimize exhaust flow and sound quality. The patented core shape effectively lowers sound levels while maintaining peak power, providing a balanced combination of performance and noise reduction. The innovative canister shape increases internal volume, allowing for more sound-absorbing material that results in a refined exhaust note. The chamber design is tailored to enhance and refine exhaust pressure, improving throttle response and overall engine efficiency.

Factory forward engineering centralizes mass to reduce the risk of crash damage and improve handling. Each system is tuned with application-specific core specifications, ensuring optimal performance for your particular riding style and bike setup. The rear end cap design allows for easy installation of tuning tip inserts or spark arrestors, making adjustments straightforward without extensive modifications. The FMF Factory 4.1 RCT is available in two configurations: Titanium (Ti RCT) with a titanium canister and mid-pipe, and Aluminum (Aluminum RCT) with an aluminum canister and stainless mid-pipe. Both options include a spark arrestor and wash plug, meeting safety and environmental standards.

Whether you're racing or trail riding, the FMF Factory 4.1 RCT provides a significant upgrade over stock systems, ensuring your bike performs at its best with less weight and improved exhaust flow.
