The all new Rapid Flow exhaust kits from Bully Dog Technologies incorporates the high flow 6" radius design with the anti-corrosion protection of aluminized steel. These kits are available for Dodge, Ford, and GM full sized diesel pickups. All kits also come with stainless steel tips to complete your exhaust.

These Rapid Flow Exhaust Systems are designed and built with absolute minimal degree angles on bends; the exhausts are bent on a 6 inch bend radius. The effect is the most free flowing low back pressure system in the industry. The benefits of improving air flow to this degree include: increased horsepower and torque, improved fuel economy, and reduced exhaust gas temperatures. This kit is a 4" Single Aluminized Turbo Back Exhaust Kit that includes the tip for Ford 7.3 L F-550 '99-'03 trucks.

Increased Horsepower and Torque

Dyno Testing shows an increase of 15-20 horsepower and 30 to 40 lbs. ft. of torque. All testing was performed on a Superflow chassis dynamometer.

Superior Exhaust Pipes

4" diameter ensures more air volume than the OEM system.

6" radius bends: The tighter the corners in the exhaust piping the harder it is for the exhaust gas to flow through the pipes. By using a 6" radius bend we help to maximize exhaust flow for the vehicle. These low angle bends reduce obstruction in the exhaust pipes which encourages high air flow.

Aluminized Steel- provides better heat and corrosion resistance

Easy Installation

Installation only require basic hand tools

This kit does not require any auto mechanic experience; it can be installed by an unexperienced end user.

Stainless Steel Tip Included

Bolt-on for easy installation: The exhaust tip has a bolt on installation style which makes for easy installation and adjustment.

Professional Installation is Recommended.
