D&D Performance Exhaust introduces our NEW Slash-cut and Straight-cut slip-ons specifically designed for the Harley-Davidson Dyna. They improve power and torque for as much as 12 additional horses and puts out the great Harley rumble. Performance baffles are included.

Fits great with stock heat shields and no ECU programming is necessary. Slip-ons are tested on our state-of-the-art in-house dynamometer in combination with a high-flow air cleaner.
