Exhaust silencer FMF Q4 — Yamaha YFZ 450 R 2009–2026 and others (4T)

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.
