Upgrade the performance and race-ready appearance of your compatible Honda sport ATV with the FMF Factory 4.1 RCT Slip-On Exhaust System. Designed for the Honda TRX450R, this exhaust incorporates FMF Resonance Chamber Technology™ both internally and externally to deliver substantial power gains throughout the RPM range. Its shorter overall design helps reduce exposure to crash damage while supporting FMF Factory Forward Engineering by positioning the muffler closer to the engine for improved mass centralization.
The FMF Factory 4.1 RCT is manufactured entirely at FMF’s Southern California facility using aerospace-grade materials and a proprietary alloy-grade titanium blend developed to FMF’s exacting standards. The system also includes FMF’s Rapid Tuning System (RTS), allowing tuning adjustments to better suit specific riding conditions and performance requirements. Its lightweight construction helps reduce overall vehicle weight without compromising the durability expected for demanding off-road and racing applications.
This FMF exhaust is a slip-on system designed to fit 2006, 2007, 2008, 2009, and 2012–2014 Honda TRX450R models.
