About this product
Unleash the full potential of your machine with the FMF Factory 4.1 RCT Exhaust System. This full system delivers unparalleled performance, durability, and a distinctive sound that sets you apart from the competition.

Description
The FMF Factory 4.1 RCT Exhaust System utilizes Resonance Chamber Technology (RCT) featuring a patented core shape to reduce decibels while maximizing power output across the entire power range. Internal ducts increase internal volume, optimizing exhaust flow for noticeable power gains. FMF's Factory Forward Engineering centralizes mass, minimizing the risk of damage in case of a crash. The innovative rear end cap allows for easy installation of tuning tip inserts or a spark arrestor with the removal of just four screws. The system is constructed from a combination of high-quality materials, including a stainless steel header and an aluminum muffler body with a carbon fiber end cap, ensuring both performance and longevity. Meets AMA and FIM sound requirements with included QuietCore 94 dB insert.
