D&D Performance Enterprises of Ft. Worth, Texas, announces Boarzilla and Fat Cat exhausts for 2007 Harley-Davidson tourers powered by the TC 96" and 110" Screamin' Eagle engines, which have a new fuel-injection system that has an oxygen sensor to adjust to changing conditions. Both exhausts include pre-installed oxygen sensor ports as direct fitment and are dyno-tuned with a Super Flow Bench and Lambada sensors for maximum performance and rumble.

Identical except for the muffler cut, Boarzilla pipes are designed for big-inch engines while Fat Cats are for 96" engines. Offered in chrome or ceramic black and encased in a full-wrap heat shield, they are available from Custom Chrome dealers or D&D at 817-834-8961.
