§ 02 / About this part

What it is

The FMF POWERBOMB HEADER STAINLESS STEEL HONDA, mid pipes. Stocked by Iron Offroad, the UK MX hard parts specialist.

This stainless steel header uses a unique internal module to increase exhaust flow. The design creates a vacuum effect that pulls spent gases out of the cylinder more efficiently. It provides a noticeable boost to mid-range torque while slightly lowering the decibel output. The stainless construction handles the high heat cycles of a four-stroke engine better than stock mild steel. It fits directly to your OEM silencer or a compatible slip-on. Use a new copper crush gasket at the exhaust port to prevent leaks. This is a robust upgrade for riders seeking more tractable power.

§ 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.
