Not to sound relentless or anything, but I talked with my one of my dad's mechanics the other day (he own's a shop in lancaster co.) who is certified to do the emissions testing. For new cars like ours, its really not that big of deal. According to him the emissions aren't even tested. The machine hooks up to the car's computer and just makes sure everything is "there" and ok. I guess it looks for codes for burnt cats and what not. But anyway, as long as your computer isn't malfunctioning and you haven't messed with the cats too much, aftermarked exaust shouldn't be a problem unless the mechanic is a real prick
