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 both the 4”
Rapid Flow Aluminized Exhaust and 4” Rapid Flow 4” Ceramic Coated ‘03-’04 designed specifically for the
5.9L Cummins.
Note: This instruction set and the Rapid Flow Exhaust system included is made exclusively for the 5.9L
Cummins ‘03-’04. In 2004 Dodge introduced a new engine half way through the model year. These in-
structions cover the early 2004 models without the catalytic converter.
