Product Details

The PowerCore 4 is FMF's proven 4-stroke slip-on muffler — built tough and tuned for noticeable mid-range gain. A direct bolt-on for stock head pipes, the PowerCore 4 is the go-to upgrade for riders who want a real performance bump without going to a full system.

  • 4-stroke direct slip-on muffler
  • Lightweight aluminum canister with stainless endcap
  • Tuned for mid-range power gain over stock
  • Repackable
  • Fits OEM head pipe

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

  • Yamaha WR250F (2007-2013)
  • Yamaha WR450F (2007-2011)
  • Yamaha YZ250F (2006-2009)
  • Yamaha YZ450F (2006-2009)

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.
