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.

The D&D Low Cat 2-into-1 exhaust system is an excellent choice for engines with performance modifications from stock to plus-25% displacement, delivering a torque curve that is high and wide, with a strong top-end pull. Excellent workmanship inside and out; broad power design really shows up on the dyno.
