FMF PowerBomb Header Pipe — Yamaha YFZ 450 R 2009–2026 and others (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 YFZ 450 R (2009–2026); Yamaha YFZ 450 RSE (2009–2020); Yamaha YFZ 450 X (2010–2011); Yamaha YFZ 450 XBB (2010); Yamaha YFZ 450 XSE (2011). Specifications — material: Stainless Steel, finish: Natural. 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: 044298.
