Exhaust silencer FMF Q4 — Yamaha WR 250 F 2007–2013 and others (4T)

Description

The FMF Q4 is a quiet four-stroke silencer. The Q series is built around precisely placed baffles and chambers that absorb sound — the power stays, the noise drops. Practical where you ride close to houses or where limits apply. A twin-stage core lowers sound output and extends packing life. Less mass improves the power-to-weight ratio. Developed over years of championship off-road racing. Fits: Yamaha WR 250 F (2007–2013); Yamaha WR 450 F (2007–2011); Yamaha YZ 250 F (2006–2009); Yamaha YZ 450 F (2006–2009). Specifications — muffler material: Aluminum, pipe material: Stainless Steel, end cap material: Stainless Steel, muffler finish: Raw, weight: 2,77 kg. Note: does not meet the 2025 FIM sound limit — intended for practice and closed courses, not for FIM-sanctioned racing. Delivery 5–8 working days. SKU: 044232.
