i dont want to speak about anywhere else, but where i come from all they do is check to see if the cat is physically on the car. they dont take apart the exhaust and look inside or anything, just take a quick look-see under the car to make sure the thing is there. the one thing that might be a problem is the mileage on your car, cause its technically a fellony to change your cat prior to 50K miles, so if your car has less than that and they see a brand new cat they might say something. i say all this in an area that doesnt have emissions so i dont know what they might do in a place that does have it. but i think you'll be aight...
