The new Rapid Flow DPF exhaust kit from Bully Dog Technologies incorporates the high flow 5” design with the anti-corrosion protection of aluminized steel. This kit fits the 08 Ford 6.4L full sized diesel pickups that have a diesel particulate filter.

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 affect 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.

Dynamometer results have shown a gain of 15-20 horsepower simply by switching from stock to a Rapid Flow Exhaust System.

All kits come with an exhaust tip included. These exhaust tips are a bolt on ceramic coated tip, the ceramic coating ensures that the tip will not discolor or corrode and comes with a lifetime warranty. The bolt on style of tip installation makes installation, and adjusting extremely easy.

This exhaust kit will not affect the Diesel Particulate Filter in any way other than to encourage air flow through the filter. Our testing does not show any negative affects to the DPF.
