The FMF Factory 4.1 RCT exhaust system is engineered for Yamaha YZ250F and YZ250FX models from 2019 to 2024. Incorporating advanced Resonance Chamber Technology, this exhaust enhances performance while maintaining a refined sound profile. The patented core shape reduces noise levels without sacrificing power output, ensuring optimal engine efficiency. Its patented canister design increases internal volume, allowing for more sound-absorbing material that contributes to quieter operation and improved rider comfort. The chamber design is specifically tuned to optimize exhaust pressure, resulting in better throttle response and increased horsepower.

FMF's factory forward engineering approach centralizes mass, making the exhaust more resilient to crash damage and improving overall durability.

An innovative rear end cap provides easy installation of tuning tip inserts or spark arrestors, giving riders versatility to customize their setup. The canister and mid-pipe options include titanium or aluminum variants—each selected for lightweight strength and durability. The titanium version features a titanium canister and mid-pipe, ideal for weight-conscious riders, while the aluminum variant combines an aluminum canister with a stainless steel mid-pipe for added longevity.
