If you have OBD-II tuned well and they dont look under the car then shouldnt be of issue. If the cats are deleted then you are going to have to watch for the smell. I got lucky no one asked questions when the guy at a local gas station fired it up, heard the cam, and smelled the exhaust. My computer passed with flying colors so he just threw on the new sticker.
