§ 02 / About this part
What it is
The FMF MUFFLER PCORE 4 HEX, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
This muffler provides a significant increase in power and torque for your 4-stroke. The hex-shaped aluminium canister is designed for durability and improved internal volume. It features a stainless steel mid-pipe that resists corrosion and handles high heat cycles. This slip-on mounts directly to your stock header. It is a practical choice for riders moving away from a heavy or damaged OEM unit. Monitor the packing intervals to prevent the canister from overheating. Proper maintenance ensures the exhaust remains within sound limits while providing consistent engine performance throughout your moto.
