§ 02 / About this part

What it is

The FMF EXHAUST ALUM F4.1 RCT CARBON CAP SS MB HEADR/MID YZ450F, full systems. Stocked by Iron Offroad, the UK MX hard parts specialist.

This full system replaces the stock header and silencer to improve exhaust scavenging. It uses stainless steel and aluminium for a balance of strength and weight. The Resonance Chamber Technology reduces noise while maintaining high flow. It is a robust choice for track and trail use. Fit a new gasket at the head to prevent air leaks. Ensure the mid-pipe is seated fully before tightening the clamps. This system is designed to withstand the vibration and impacts of off-road racing. It provides clear gains in mid-range pull.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron stable — this is a UK shop for motocross, enduro, and trail-bike hard parts. All fitments live on the site, and listed against MX models KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is in the data, fully enriched to assist with accurate fitting and finding the right part for your bike quickly and easily. 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 & e-moto only. We operate from our huge storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. We have a RICH motorcycle history with multiple moto brands the images showing where we came from and our history, the business recently pivoted into hard parts and online retail.
