Hey guys, I just bought a 2003 3500 4x4 6spd Quad Cab, and it has a aftermarket exhaust on it. My question is did these trucks com with cats, resignators or nothing? I have to take it through emissions here in CT, and don't want to fail because there is'nt a cat if it's supposed to have one. Currently it just has a 4" exaust with a muffler, so there is no sign of a cat. Also do you guys with the sticks experience gear roll over much? I noticed it quite abit when you're off the throttle letting the transmission pull you along. Thanks
