08' DPF-Back Rapid Flow Exhaust System:

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. These kits are available for ‘07.5-’08 Dodge, Ford, and GM 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.

These exhausts are also extremely easy to install. The stock exhaust from the DPF back can easily be unbolted and removed in under 20 minutes. Installing the Rapid Flow Exhaust System is very simple, all of the hangers are welded on to the exhaust system which takes the guess work out of positioning the exhaust.

What about the DPF:
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; all DPFs worked as they were designed to do so by the OEM manufacturer throughout our entire testing cycle.
