FMF Stainless MegaBomb Header — Yamaha WR450F (2019-2020), Yamaha YZ450F (2018-2019) + 1 more, 4-Stroke
Product Details

The MegaBomb is FMF's largest resonance-chamber header — a larger expansion volume than the PowerBomb for even broader low-end and mid-range gains. Stainless steel version offers rugged durability at a friendlier price than the titanium MegaBomb.

  • Larger resonance chamber than PowerBomb — bigger low-mid bump
  • Stainless steel construction
  • Direct-fit replacement for OEM head pipe
  • Pairs with FMF 4-stroke slip-ons
  • Mandrel-bent for smooth flow

Fitment: 4-stroke bike specific — fits the following models:

  • Yamaha WR450F (2019-2020)
  • Yamaha YZ450F (2018-2019)
  • Yamaha YZ450FX (2019-2020)

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.
