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 10-20hp 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.

16-gauge aluminized comes in the widest range of sizes and comes with a one year warrantee.

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 their new 6” systems are recommended for trucks producing more than 550 hp
