FMF Racing - KTM 4.1 RCT Aluminum S/O w/Carbon Cap

Highest-quality proprietary blend of alloy grade titanium

The FMF Racing Factory 4.1 RCT Slip-On Exhaust is engineered to deliver massive power gains and lightweight performance for your bike, incorporating the latest FMF Resonance Chamber Technology™ (RCT). This cutting-edge technology, used both internally and externally, maximizes power delivery across the entire RPM range while ensuring a shorter overall length that’s less vulnerable to crash damage. In line with Factory Forward Engineering, the system moves the muffler closer to the motor to centralize mass, enhancing bike balance and handling.

Constructed from aerospace-grade materials, including a Blue Anodized Titanium Muffler with a carbon end cap, the Factory 4.1 RCT offers huge weight savings without sacrificing performance. The Rapid Tuning System (RTS) allows for easy adjustments, enabling you to fine-tune your setup for optimal performance. Built entirely in FMF’s Southern California factory, this exhaust is the perfect balance of strength, performance, and durability.
