Upgrade the exhaust performance of select KTM and Husqvarna off-road motorcycles with the FMF Ano Ti Factory 4.1 RCT slip-on exhaust, manufacturer part number 045648 and vendor part number 79-40417. This tuned exhaust uses FMF Resonance Chamber Technology to help reduce sound levels while maintaining strong power output. Its patented core, canister, and chamber designs work together to refine exhaust pressure, increase internal volume for sound-absorbing material, and deliver application-specific performance.
The titanium canister and mid-pipe provide a lightweight construction suited to demanding trail and enduro use. FMF Factory Forward Engineering centralizes mass to support improved handling and helps reduce the likelihood of crash damage. An innovative rear end cap allows straightforward installation of tuning tip inserts or a spark arrestor, while the included spark arrestor and wash plug add practical trail-use functionality. The Ano Ti Factory 4.1 RCT is designed as a direct-fit slip-on replacement for compatible original equipment exhaust systems.
