FMF PowerBomb Header — Yamaha WR450F (2003-2006), Yamaha YFZ450 (2004-2015) + 1 more, 4-Stroke
Product Details

The PowerBomb header is FMF's bolt-on resonance-chamber header pipe. The PowerBomb chamber sits inline between the engine and the muffler, smoothing exhaust pulses for a broader, more usable powerband. Stainless steel construction with mandrel-bent tubing.

  • Inline resonance chamber for broader powerband
  • Stainless steel mandrel-bent construction
  • Direct-fit replacement for OEM head pipe
  • Pairs with any FMF 4-stroke slip-on
  • Race-developed geometry

This is a 4-stroke exhaust. It is engineered for the 4-stroke engine architecture above and physically will not fit a 2-stroke bike. Verify your engine type before purchase.
