KTM/Husq F4.1 Slip-On
FMF Racing Factory 4.1 RCT mufflers offer the latest technology inside and out. Hand-built using aerospace-grade materials, they feature Resonance Chamber Technology. FMF's patented core enhances and refines exhaust pressure waves for optimal power output, while lowering the sound levels. Their redesigned canister shape allows for a maximum volume of packing material that's formulated for durability and sound attenuation. Plus, their RTS (Rapid Tuning System) makes for easy sound insert changes, as well as adding US Forestry Approved Spark Arrestors. They're constructed using aerospace-grade materials, run quieter than stock, and gain huge weight savings and massive power throughout the rpm range.
