How did you pay--I'm assuming cash? Did you get a receipt? I'm assuming if the shop installed exhaust without cats they did what they normally do--no receipt--no record that any transaction took place. Therefore, they can't get in trouble for anything. Unfortunately, this hurts you because you have no proof that they did the work if you paid cash and did not receive a receipt or invoice.
In NJ always, always put cats on your vehicle, even if they are hollowed out. NJ has those roving inspection checkpoints, and even if you have a valid inspection sticker, they can pull your car over and check. It is a pretty big fine too. They do check.
I've seen these in Glassboro, Beachwood, Tinton Falls and many other towns in NJ.
