Upgrade the exhaust performance and sound control of your compatible 250F motocross motorcycle with the FMF Aluminum Factory 4.1 RCT slip-on exhaust. Manufacturer part number 045632, this FMF exhaust features the latest Resonance Chamber Technology and a patented core shape designed to reduce sound levels while maintaining strong power output. The patented canister shape increases internal volume for additional sound-absorbing material, while the chamber design refines exhaust pressure for optimized performance.
The Factory Forward Engineering layout centralizes mass and helps reduce the exhaust system’s exposure to crash damage. This tuned exhaust uses application-specific core specifications to provide a performance-focused fit for select KTM, Husqvarna, and GasGas 250F models. The aluminum canister is paired with a stainless steel mid-pipe for a practical balance of weight, durability, and heat resistance. An innovative rear end cap allows simple installation of tuning tip inserts or the included spark arrestor.
