Exhaust Header FMF PowerBomb — Yamaha YFM 700, YFM 700 R, YFM 700 RSE 2015–2023 (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 YFM 700 (2015–2023); Yamaha YFM 700 R (2015–2023); Yamaha YFM 700 RSE (2015–2023). 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: 044432.
