the dpf is the diesel particulate filter. It is in the exhaust system on the 07.5 and 08 trucks. The "classic" 07's dont have it. It catches all the soot (black smoke) so that it doesn't go into the atmosphere. It restricts the exhaust flow a ton, and most people that take it off get a couple extra mpg's. You also will have to get a tuner that will get rid of the codes and fools the computer to make it run right.
