Firebrand Exhaust 4" Grand Prix Slip-On Muffler For Harley

The Grand Prix Slip-On is a great way to amplify the growl of your Bagger. Inspired by the MotoGP race circuit, the Grand Prix Slip-On is guaranteed to stand out with its chrome hex end treatment nesting inside a contrasting black ceramic coated billet end cap. Don’t be fooled by its good looks, the Grand Prix Slip-On is not just for show. Inside the 4” muffler body is a free flowing, stainless core baffle wrapped in dual-density packing. Engineered to bring your bike's potent power plant to life, the Grand Prix Slip-On delivers increased performance, and a sound so deep you can feel it.

Features:

  • 4” muffler body with billet aluminum MotoGP inspired end cap
  • Race-inspired high performance baffle with dual density muffler packing
