About this product
Unleash the full potential of your machine with the FMF Factory 4.1 RCT Slip-On Muffler. Engineered for performance and durability, this muffler delivers enhanced power, reduced noise, and a race-inspired design.
Description
The FMF Factory 4.1 RCT Slip-On Muffler utilizes patented Resonance Chamber Technology (RCT) to lower decibels without sacrificing maximum power. Internal ducts optimize exhaust flow, delivering noticeable power gains across the entire RPM range. FMF's Factory Forward Engineering centralizes mass, enhancing handling and minimizing crash damage. The innovative rear end cap design allows for easy installation of tuning tip inserts or a spark arrestor by simply removing four screws. Constructed from high-quality stainless steel and aluminum with a carbon fiber end cap, this muffler not only performs but also looks the part. Compatible with both stock and FMF headers, it's a versatile upgrade for serious riders.
