This thing is throaty! Has a nice deep bark when you get on it and a low rumble at idle. It's not overly loud and it's rather quiet when your just cruising along down the trail till you stab the throttle. Definitely happy with it

Questions & Answers

  • What is the decibel rating

    By: Guest

    While FMF doesn't provide an exact dB rating for the Ti PowerCore slip-on muffler. If you were install the included spark arrestor, the sound output would be no more than 96 dB at 1/3 throttle as that's the stated requirement for passing a USFS spark arrestor sound test.
