In most Harley circles, people generally feel that 2-into-2 exhaust systems look cooler than 2-into-1 pipes. Over the years, function has begun to edge in on form — pipe manufacturers have started to appease the public’s demand for better low-end power and mid-range torque by making better looking 2-into-1 systems. D&D’s new Fat Cat 2-into-1 pipe looks as good as it performs.

This beautiful system combines a huge, 4-inch high-flow muffler and stepped headers with gorgeous full-coverage heat shields. We knew the D&D;’s would look good on this ’01 Softail, but we wanted to prove they perform. Our test bike was a basically stock TC-88 with some mild jetting and a pair of private label slip-ons installed. We went over to Nigel Patrick’s Patrick Racing shop to do the installation and finished it off with a run on his Dyno.
