Description

The FMF Racing Factory 4.1 RCT Slip-On is engineered for riders seeking the ultimate blend of mass centralisation, power, and durability. Developed with FMF's proprietary Resonance Chamber Technology™ and Factory Forward Engineering, this system utilises aerospace-grade materials, delivering both weight reduction and exceptional strength. The short, robust design improves mass centrality and decreases the risk of crash damage, while a carbon end cap and stainless steel midpipe ensure outstanding longevity and aesthetics. Manufactured entirely at FMF’s Southern California facility, this premium slip-on offers serious power gains across the RPM range for demanding off-road applications.

Features

Closed course competition use only for maximum performance
Robust slip-on configuration with single outlet
Aerospace-grade aluminium construction with carbon fibre end cap for strength and lightweight
Rapid Tuning System (RTS) streamlines setup and adjustments
Reduced weight improves handling (7.8 lbs)
Substantial power and torque enhancements across all revs
Includes screen-type spark arrestor and 94dB quiet insert
Premium stainless steel midpipe for resilience and corrosion resistance
