If you're looking for a new exhaust system for your 2007 Harley-Davidson touring bike, D&D Performance Exhaust has something for you. Here's their press release from yesterday...

D&D Performance Enterprises is shipping dyno-tuned Boarzilla and Fat Cat 2 into 1 exhaust pipe systems for the all new 2007 Harley-Davidson Twin Cam 96 and 110 Screamin' Eagle engines equipped in their touring line of motorcycles.

Harley's touring motorcycles are outfitted with a new fuel-injection system that comes with an oxygen sensor to adjust to changing environmental conditions. D&D performance exhaust pipes include preinstalled stock factory oxygen sensor ports as well as direct fitment with no cutting, welding or grinding.

The new 2 into 1 high-performance Boarzilla and Fat Cat pipes and slip-ons improve power and torque on the entire touring family of motorcycles, which includes the FLHR Road King, FLHRS Road King Custom, FLHRC Road King Classic, FLTR Road Glide, FLHX Street Glide, FLHT Electra Glide Standard, FLHTC Electra Glide Classic and FLHTCU Ultra Classic Electra Glide.

The 2 into 1 Boarzilla and Fat Cat pipes are identical in appearance except for the muffler cut but are customized on the inside to accommodate modification of the Harley-Davidson Twin Cam engines. The Boarzilla pipes are designed for big-inch and Screamin' Eagle engines.
The Fat Cat pipes are manufactured for 96 engines.

Both pipes are dyno-tuned for maximum performance, rumble and encased in a full wrap heat shield that keeps all discoloration from view. D&D performance pipes are delivered in show-quality chrome or ceramic black.

"The new TC96 engine still looks pretty much the same on the outside, but there's a lot that's new on the inside," said Dave Rash, President of D&D Performance Exhaust Enterprises. "We took our time to wring out performance and deliver that sweet Harley sound that our customers tell us that they want."

Factory Harley-Davidson dealerships are increasingly finding that D&D Performance Enterprises delivers the value to their customers. "We have four criteria in carrying a pipe in our dealership that includes performance, fit, finish and heat shields," said Walter Birmingham, Assistant Parts Manager, Mancuso Harley-Davidson Houston. "They meet all of our criteria and if they didn?t meet the performance standards we wouldn?t recommend them. They are that good. They consistently out perform Samson, Reinhardt and Hooker."

These 2007 Harley-Davidson pipes are torture tested on D&D's state-of-the-art in-house Super Flow Eddy Current Ram Air dynamometer.
This is done in combination with the Super Flow Bench and the first in the industry, multi cylinder Lambda Fuel Air Ratio Sensors, which are interfaced with the Dyno for real time meter and graph analysis. This means that performance is always increased with a D&D exhaust pipe.

The dyno chart and dyno video with audio clip for both the Boarzilla and Fat Cat style Harley performance exhaust pipe is located on the website in the catalog section at

D&D Performance Exhaust has sold over 250,000 exhaust systems in the past 30 years. Visit them at:
