    Great quality fit and finish.

    Everything I was hoping they would be. Great sound, fit and finish. Not much louder than stock at idle but nice deep rich tone under load. Perfect amount of rumble while cruising not offensive but enough for others to know a motorcycle is near.

    High quality mufflers

    They look good and sound great even with the db reducers installed.
