Let us help make your diesel truck the undisputed leader of the pack. The Bully Dog Rapid Flow Diesel Dual Exhaust cranks-up your horsepower, boosts pulling torque and toughens your truck’s sound—all while reducing exhaust gas temperature up to 200°.

Precision mandrel-bent pipes provide each of these performance upgrades, virtually eliminating backpressure and creating free airflow. Plus, the Bully Dog Rapid Flow Diesel Dual Exhaust showcases the sweet look of dual side exits.

Crafted from aluminized steel in a 4” diameter, the Bully Dog Diesel Dual Exhaust completely replaces limiting stock systems. Straightforward installation in 2 hours or less requires cutting-off the stock exhaust and bolting-on the Rapid Flow to factory mounting positions.

Systems come in multiple configurations with single and dual set-ups, they are available in three tubing sizes, 4 and 5 inch tubing. Systems are also available from the turbo back, catalytic converter back and for the new diesels from the diesel particulate filter back.

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.
