Harley Sportster: D&D Bob Cat Exhaust

Harley-Davidson Sportster Exhaust

D&D has released the 2004 through 2011 Bob Cat Sportster Pipe that pumps out performance, torque and a soul-satisfying tone. The 2-into-1 full pipe comes equipped with heat shields and a flawless finish in black or chrome.

Enthusiasts also can select the materials and finishes on the Sportster Bob Cat muffler. The end caps are available in black or chrome with the canister offered in polished aluminum, black or carbon fiber. Bob Cat works with both mid-controls and forward-controls.

D&D Performance Enterprises is using their new Concentric Flow Baffle System on the Bob Cat pipe. This new and innovative baffle system was first introduced on the 2009 Harley-Davidson bagger line. Applied to the Sportster line, it improves torque and horsepower by as much as 10% as well as reducing the bark at WOT.

The new baffle technology is derived from collaboration with the University of Texas at Arlington Mechanical & Aerospace Engineering department. Dr. Bob Woods and his students worked with D&D to deliver the exhaust trifecta – reduced noise, performance improvement and enhanced Harley-rumble.

D&D provides a performance kit option for the Harley-Davidson Sportster that includes a Bob Cat and a Zipper’s HiFlow air cleaner. This combination for the Harley-Davidson Sportster delivers the greatest bang for the performance-minded buck.

About D&D Performance Exhaust
In 1972 David Rash could not find the exhaust pipe he needed for his race bike. He knew that the proper exhaust for his engine configuration would give him an edge over his competition so he fabricated one himself. Thirty years and 250,000 pipes later, D&D Performance Exhaust systems are some of the leading performance motorcycle exhaust systems in the world.
