That said, when I had my truck emission tested, he never looked at my exhaust, it was all aftermarket, from when I lived in Illinois at a auto shop and had a nice magnaflow cat, all 4 of the stocks where taken off and sold for the price of the full exhaust, and still passed emissions by a very good amount.. And that's all he cared about..

Figured at much. Around here they just throw a tool onto the ODBII port and run the car at 3k RPMs and see if it throws any codes. A tune could remove the codes, so I guess I will need to save up some more scratch later on this year.
