§ 02 / About this part

What it is

The FMF FACTORY 4.1 RCT ALUMINUM S/S SLIP-ON MUFFLER W/ CARBON END CAP, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This slip-on muffler replaces the stock unit and connects directly to your OEM header pipe. It utilizes a resonance chamber to refine power delivery across the rev range while keeping sound levels within track limits. The aluminium canister and stainless steel mid-pipe offer a robust build for enduro or motocross use. It is a direct fitment that requires no modifications to your subframe. Check the joint between the header and the mid-pipe for a secure seal. Regular maintenance of the internal packing ensures the bike retains its throttle response and stays quiet enough for UK venues.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron Stable — a UK shop for motocross, enduro, and trail-bike hard parts. Every fitment lives on the site, listed against KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is the data: fully enriched fitment so you find the right part for your bike quickly and get it fitted accurately. Brands you'd find on a paddock workbench — pads, sprockets, plastics, fork seals, cables, gaskets, bars, the things that actually wear out. Road-bike kit, scooter parts, and quad gear sit elsewhere; dirt and e-moto only. We operate from our storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. The business has a rich motorcycle history across multiple moto brands — the photos show where we came from — and recently pivoted into hard parts and online retail.
