§ 02 / About this part

What it is

The FMF MUFFLER P-CORE 4 HEX, slip-ons. Stocked by Iron Offroad, the UK MX hard parts specialist.

This muffler delivers a significant boost in horsepower and torque for your 4-stroke bike. The hex-shaped canister increases internal volume for better flow and a deeper sound. It replaces the heavy factory silencer and mounts to the existing subframe points. The stainless steel and aluminium construction ensures durability in harsh off-road conditions. Use a new exhaust gasket or high-temp sealant at the join to prevent leaks. This slip-on is a reliable way to improve engine response for both MX and trail riding. Regular repacking will maintain the power gains and sound quality.

§ 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.
