FMF Racing has a new slip-on exhaust for 2024-26 KX450F/KX450X models.

The Factory 4.1 RCT Titanium exhaust ($899.99) is anodized blue and comes with a carbon-fiber end-cap. Constructed from aerospace-grade materials and manufactured at FMF’s SoCal factory, the exhausts utilized FMF’s Resonance Chamber Technology to optimize power output.

Performance and sound output can be tailored with FMF’s Rapid Tuning System, and the mufflers are shorter than the stock unit for a centralized mass, which makes them less susceptible to damage in a tipover.

Factory 4.1 Titanium Key Features
- Titanium construction for reduced weight
- Maintain OEM mounting positions while improving power
- Power & torque gains with increased horsepower across the rpm range
