Noise reducers available for Stealth mufflers only. Please confirm whether your muffler is a 2" or a 2.25" opening. If you are not sure if your muffler is Stealth or Supersport, you can check the inside of the muffler on the End Cap/outlet side. If you can see perforated material right away, this is a STEALTH muffler. If the perforated material starts further back inside the muffler, this is a SUPERSPORT muffler.
Noise reducer insert for Hindle Stealth mufflers. Will not fit Hindle Evolution mufflers. Quiets down your Hindle Stealth muffler by 2-3 decibels less. Easily inserts into the core of the muffler and can be removed when not needed.
