The HD® Dyna® platform may have ceased production, but they remain an important part of the custom scene and companies like S&S Cycle continue to make cool parts for them! Their latest includes slip on mufflers in two different formats designed to look good and make big power. The Grand National version is styled after their flat track race mufflers and the Slash Cut is a clean interpretation of a classic shape. Both include their removable dB Reducers that allow riders to fine tune the sound for the perfect exhaust note. Both are also available in ceramic black or chrome and both promise a 17% gain in Hp. Fitment from 1995 to 2017, on most Dyna models.
