Overview Specs


  • 4.5" slip-on mufflers for 2017 and later Harley Touring models

  • Proprietary baffle that’s engineered specifically to increase and enhance the sound of the M8 engine, while providing a free-flowing exhaust and the perfect amount of backpressure, unlocking both horsepower and torque.

  • Available in our 4.5” Muffler body, which gives your bike a louder, bass heavy tone that never sounds muffled or flat.

  • Finished off with our popular Tradition end caps, this muffler has a look that is as big as its sound, and perfectly complements the style of the M8 Bagger.

  • Not recommended for Ultra Limited.

  • 100% American made and backed with our Forever Warranty, guaranteeing the quality that Rinehart is known for the world over.

  • Performance baffle sold separately for riders who already have our 4" or 4.5" Slip-Ons on their M8 Touring bike.
