Exhaust Part FMF PowerBomb — Yamaha WR 250 F, YZ 250 F 2001–2013 (4T)

The FMF PowerBomb is a four-stroke header with FMF's patented chamber placed right at the start, just behind the head. The expansion and contraction of the gases at that point increases flow — power can rise by as much as 10%. The chamber also works as a pre-muffler and helps bring the system's sound output down. Fits: Yamaha WR 250 F (2001–2013); Yamaha YZ 250 F (2001–2006). Specifications — material: Stainless Steel, finish: Natural. Delivery 5–8 working days. SKU: 040073.
