Description
The FMF Factory 4.1 RCT Exhaust System features Resonance Chamber Technology (RCT), utilizing a patented core shape to reduce decibels while optimizing power output. Internal ducts increase internal volume, enhancing exhaust flow and boosting performance throughout the rev range. FMF's Factory Forward Engineering centralizes mass, providing improved handling and reduced vulnerability to crash damage. The innovative rear end cap allows for quick and easy installation of tuning tip inserts or a spark arrestor with just four screws. This system is constructed from high-quality titanium for both the muffler and pipe, and features a carbon fiber end cap. The blue anodized titanium muffler adds a stylish, high-performance look to your bike. Meets AMA and FIM sound requirements and includes a QuietCore 94 dB insert.
