About this product
Unleash the full potential of your machine with the FMF Factory 4.1 RCT Slip-On Muffler. This high-performance exhaust upgrade delivers increased power, reduced noise, and enhanced durability, making it the ideal choice for serious riders and racers.
Description
The FMF Factory 4.1 RCT (Resonance Chamber Technology) slip-on muffler utilizes a patented core shape to effectively lower decibels while maximizing power output. Internal ducts strategically placed within the chambers of the RCT system optimize exhaust flow by increasing internal volume, resulting in significant power gains throughout the entire RPM range. FMF's Factory Forward Engineering centralizes mass, reducing the risk of damage in the event of a crash. The innovative rear end cap simplifies the installation of tuning tip inserts or a spark arrestor with the removal of only four screws. This muffler meets AMA and FIM sound requirements, ensuring compliance without compromising performance. Upgrade to the FMF Factory 4.1 RCT and experience the difference.Features & highlights
