Product Details

The Titanium MegaBomb is FMF's lightest, top-tier resonance-chamber header. Aerospace-grade titanium construction shaves weight off the front of the bike while delivering the broader powerband of the MegaBomb expansion volume.

  • Largest FMF resonance chamber — wide low/mid power
  • Aerospace-grade titanium — lightest configuration
  • Direct-fit replacement for OEM head pipe
  • Pairs with FMF 4-stroke slip-ons
  • Made in Southern California

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.
