Thoroughbred Diesel is now offering a free shipping special on Bullydog rapid flow diesel exhaust systems. We have a large amount of Bully Dog performance products in stock to ensure fast delivery. 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.

Add some extra growl to your diesel truck! Your Bully Dog Rapid Flow Diesel Dual Exhaust is covered by a 2-year warranty.

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.

Available in 16-gauge aluminized, T-304 micro shine stainless steel or T-409 stainless steel.

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.
