About this product
Unleash the full potential of your machine with the FMF Factory 4.1 RCT Exhaust System. This full system exhaust is engineered to deliver maximum power gains across the entire RPM range while minimizing noise. The Factory 4.1 RCT is a top-tier exhaust system designed for riders who demand the best in performance and durability.
Description
The FMF Factory 4.1 RCT (Resonance Chamber Technology) exhaust system features a patented core shape that effectively reduces decibels without sacrificing power. Internal ducts increase internal volume, optimizing exhaust flow and boosting overall performance. FMF's Factory Forward Engineering centralizes mass, enhancing the bike's handling and reducing the risk of damage in the event 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. Constructed from premium titanium with a carbon fiber end cap and an anodized blue finish, this full system not only performs exceptionally but also looks stunning. The FMF PowerBomb header is included to maximize exhaust flow and increase horsepower and torque.
