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 improved power, reduced noise, and enhanced style.
Description
The FMF Factory 4.1 RCT Slip-On Muffler utilizes Resonance Chamber Technology (RCT) with a patented core shape. This design effectively lowers decibels while maximizing power output. Internal ducts increase internal volume, improving exhaust flow and providing power gains across the entire power 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 just four screws. Compatible with both stock and FMF headers, this slip-on muffler offers versatile performance upgrades. Available with a blue anodized finish and carbon fiber end cap. Meets AMA and FIM sound requirements.
