The FMF Aluminum Factory 4.1 RCT Slip-On Exhaust is designed to improve exhaust performance while maintaining controlled sound levels across select KTM and Husqvarna motocross and off-road applications. This tuned exhaust system uses FMF Resonance Chamber Technology and application-specific core specifications to optimize exhaust pressure, helping deliver strong, usable power output. The aluminum canister is paired with a stainless steel mid-pipe and a carbon end cap for a durable, performance-focused configuration.
Patented internal features help increase sound-absorbing material capacity and refine exhaust flow without compromising performance. Factory Forward Engineering centralizes mass within the motorcycle and helps reduce the likelihood of crash damage. The innovative rear end cap supports straightforward installation of tuning tip inserts or the included spark arrestor. A wash plug is also included to help protect the exhaust system during routine motorcycle cleaning.
