DPF Back Exhaust Systems for Dodge, Ford, GM Trucks

DPF Back Exhaust Systems are one of the most popular aftermarket improvements made to diesel trucks. They remove the stock muffler and turbo, catalytic converter, and remove the majority of the exhaust's noise. They basically just help with the flow of exhaust and therefore create a more pleasant sounding truck.

More on DPF Back Exhaust Systems from OC Diesel:

Some of these systems even lower the tailpipe's temperature during regeneration, which is when the tailpipe heats up extra hot in order to vaporize the soot trapped within. A DPF Back Exhaust System is one of the simplest ways to improve your vehicle's performance and make it sound great.
