INTRODUCTION
The Bully Dog Rapid Flow Exhaust Systems have been specially designed to allow the lowest mandrel
bends in the industry. The lower mandrel bends allow increased air flow which reduces exhaust tem-
peratures, improves engine efficiency and increases horsepower. This instruction set covers the 4” Rapid
Flow Aluminized Turbo Back Exhaust and the 4” Rapid Flow Ceramic Coated Turbo Back Exhaust designed
specifically for the 5.9L Cummins, both systems install the same way.
