Dominate the Track with FMF’s Factory 4.1 RCT Complete Exhaust System for Husqvarna

Engineered for serious motocross and enduro riders demanding peak performance, the FMF Factory 4.1 RCT System revolutionizes your Husqvarna’s power delivery and handling. At its core is the proprietary Resonance Chamber Technology™ (RCT), meticulously integrated both inside and out. This advanced design doesn’t just boost power – it creates massive, usable gains across the entire RPM range, giving you explosive acceleration out of corners and relentless pull on straights.

FMF’s innovative Factory Forward Engineering philosophy is key here. By strategically shortening the overall system length and positioning the muffler closer to the engine mass is centralized. This translates directly to superior bike balance and reduced susceptibility to crash damage – crucial advantages when pushing limits on rough tracks or technical trails.

Crafted exclusively from premium, aircraft-grade materials meeting FMF’s stringent standards, every component is built to endure the harshest riding conditions. Proudly manufactured 100% in Southern California, quality is guaranteed.
