D&D slip-on mufflers provide more power and torque while enhancing that great Harley® sound. Their slim 2-1/2” diameter flows smoothly from the headpipe heat shield’s diameter to give the look of a continuous system while retaining the factory headpipe. Specially designed removable baffles give off a deep, rich rumble. Choose traditional side slash-cut, back-cut or straight cut for the ‘big shotgun’ look. These mufflers are sold in sets, finished off in show quality chrome or black.

D&D’s newest Bob Cat pipe design increases power with improved tone while enhancing the Harley® boom. D&D's wrapped Big Bore baffle produces the signature sound of the pipe (plenty of bark!) and increases performance. Upswept 2:1 Bob Cat pipe includes chrome or black headpipes and is offered with an Aluminum, Black or Carbon sleeved muffler. The Bob Cat system increases ground clearance on lowered bikes but may not clear saddlebags. Fits models with "ribbed" oil tanks such as Rocker® and 2009 CVO Springer® models. These pipes are equipped with both 12 and 18mm oxygen sensor bungs.
