Boarzilla & Fat Cat

Also a new feature is O2 sensor bungs in all of the Fat Cat and Boarzilla Pipes, available by special order from the Factory and then standard as current inventories are restocked.

Boarzilla pipes are upswept in the back, which increases the lean angle of the bike without scraping chrome and upsetting chassis dynamics. The come with a larger head pipe to accommodate big-inch v-twin engines. Boarzilla pipes are finished with a slight slash-cut design.

The 2 into 1 Fat Cat pipes are manufactured with a standard size head pipe and shoot straight out the back. They are finished off in a pronounced slash-cut design.

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.

Each Harley Softail pipe is dyno-tuned for maximum performance, rumble and encased in a full wrap heat shield that keeps all discoloration from view. The Boarzilla and Fat Cat pipes improve power and torque by as much as 12 additional horses.

Pipe Technlogy

The Harley Softail 2 into 1 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 and D exhaust pipe.
