Product Details

When designing the PowerCore 4 HEX, we looked at our top of the line products to deliver race-inspired performance at an economical price. The end result is a quality muffler with improved torque, increased horsepower and rugged durability all at a price that won't break the bank.

  • Overall increase in power and torque.
  • Durable stainless steel and aluminum construction.
  • Space Age internal packing material for maximum longevity.
  • Internal shape of core uses Hi-Flo technology.
  • Enhanced sonic evacuation provides for higher flow and increased power.
  • Includes removable spark arrestor.

Slip-on. Replaces the stock muffler and bolts to the stock header or an FMF MegaBomb/PowerBomb header, sold separately. Header not included.

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.
