My neighbor with a 2003 duramax had the same idea about Dodge/Cummins until I left him sitting at the light in a cloud of black smoke. Then about a week later when he was taking my and his kids to the movies, he decided to tackle one of the 1500 Hemi Rams with a set of duals. First thing my kids did when they came in was told me how he was blown away so bad by a dodge truck with two pipes out back that he turned a block away from the turn off for the theater to avoid seeing the guy at the light. Priceless
