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 10-20 gain in horsepower by simply switching from stock to a Rapid Flow Exhaust System. This will also lower exhaust temperatures by as much as 200 degrees depending on size upgrade and horsepower output.
Bully Dog recommends using a 4 inch exhaust system for horsepower applications less than 450 hp, while the 5 inch systems are recommended between 450 to 550 horsepower applications, and our new 6 inch systems are recommended for trucks producing more than 550 hp.
