The D&D Softail Bob Cat design offers an upswept muffler for increased ground clearance on lowered Softail motorcycles. 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.

D&D’s philosophy is to trust their own R&D program, developing their product line to reflect what they learn during their countless hours of testing on the D&D dyno. But they didn’t stop after they made big power, they also built systems that are engineered to fit and look great! Inspect a D&D pipe, and you’ll find true craftsmanship—from the hand-ported inlets and collectors, hand-fit heat shields with machined and welded steel clamp brackets, heavy-duty mounting supports and flawless finishes, you’ll know you made the right choice for your Harley®.

All models are available in brilliant chrome or high-temperature black powder coat finish. Includes full-length header heat shields to ensure great looks over the long haul.
