§ 02 / About this part
What it is
The FMF MUFFLER FACT4.1RCT ALM, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
This muffler uses Resonance Chamber Technology to shorten the overall length while increasing internal volume. This moves the weight closer to the engine for better mass centralisation and improved bike handling. It fits directly onto the stock header or a compatible aftermarket mid-pipe. The aluminium canister provides a race-ready exhaust note and increased power across the rev range. Use the included quiet insert if you need to meet specific track noise limits. Inspect the rivets and packing every 15 hours of hard race use. This is a performance-focused upgrade for serious track riders.
