Most smog shops now will put cars on a smog dyno and run the engine at different speeds. I smoged my friends SC M3 with Cams and passed with flying colors. I thought it wasnt going to pass. If you do have a gutted exaust, you will never pass! Plus..depending where you live..DMV will require a picture of your car being smoged, running on the dyno, and the results! No I ain't no smog tech, I'm a student trained to become one!
