Description
The FMF Racing Factory 4.1 RCT Slip-On Exhaust features advanced Resonance Chamber Technology (RCT) with a patented core shape that reduces noise levels while maintaining maximum power output. The internal chamber design enhances exhaust flow, resulting in horsepower gains across the entire RPM range. Built with Factory Forward Engineering, this system centralizes mass for improved handling and durability, making it less prone to crash damage. The titanium midpipe ensures a lightweight construction, and the innovative rear end cap allows for easy installation of tuning tip inserts or a spark arrestor with just four screws. This exhaust meets AMA and FIM sound requirements and includes a QuietCore 94dB insert and a spark arrestor. The anodized titanium canister is complemented by a carbon fiber end cap for high performance and durability.
