§ 02 / About this part

What it is

The PRO CIRCUIT MUFFLER/SILENCER 304 FACTORY SOUND, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.

This silencer provides a longer canister design compared to the shorty version. It offers increased top-end over-rev while maintaining a crisp exhaust note. The stainless steel and aluminium construction resists corrosion and stands up to heavy use. It is a direct replacement for your stock silencer and works effectively with both OEM and aftermarket front pipes. Use this for open tracks where top speed matters. Check the mounting rubbers for wear when installing to ensure the exhaust remains isolated from vibration and does not stress the subframe.

§ 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.
