Exhaust Silencer FMF PowerCore 4 — Yamaha WR 250 F, YZ 250 F 2003–2006 (4T)

The FMF PowerCore 4 is a four-stroke silencer — the sensible choice when you want more power and less weight without going to the most expensive line. Elliptical aluminium canister with cross-weave internal packing for long life and even sound damping. Better exhaust evacuation means higher flow and more power. A removable spark arrestor is usually included. Fits: Yamaha WR 250 F (2003–2006); Yamaha YZ 250 F (2003–2005). Specifications — muffler material: Aluminum, end cap material: Stainless Steel, muffler finish: Natural, weight: 2,59 kg. Note: does not meet the 2025 FIM sound limit — intended for practice and closed courses, not for FIM-sanctioned racing. Spark arrestor included. Delivery 5–8 working days. SKU: 044220.
