Bully Dog 4" Rapid Flow Exhaust Systems - Dual

Bully Dog Technologies’ Rapid Flow Exhaust Systems are designed and built with absolute minimal degree angles on bends. This will create the most free flowing low back pressure system in the industry allowing the turbo to move air more freely, reducing exhaust temperatures. Dyno results have shown a significant gain in horsepower by simply switching from stock to a Rapid Flow Exhaust System.

The Rapid Flow Exhaust Systems have the lowest degree mandrel bends offering free flowing and low back pressure. This will lower exhaust temperatures by as much as 200 degrees and provides 10-20 hp increases dependent upon size upgrade and current horsepower output.

Bully Dog recommends using a 4” exhaust system for horsepower applications less than 450 hp, while the 5” systems are recommended between 450 to 550 horsepower applications, and our new 6” systems are recommended for trucks producing more than 550 hp.
