FMF Stainless MegaBomb Header — Husqvarna FE501 (2020-2023), KTM 500 XCF-W (2020-2023), 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:

  • Husqvarna FE501 (2020-2023)
  • KTM 500 XCF-W (2020-2023)

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.
