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, burns more fuel in the combustion chamber adding additional horsepower and fuel economy.
This instruction set covers the 4” Rapid Flow Aluminized Cat Back Exhaust designed exclusively for the
Ford 6.0L Power Stroke.
