Also, if you put the resonators in at a exhaust shop, take the reciept with you to court and you may get lucky. It will have the same effect as your dot exhaust that would cost 400-800 bucks. They may dissmiss it.

On another note, I don't know that what you wrote is what the law is. I didn't think GA had restrictions on what you replace. It just has to have a cat and be within the decibel limits which if yours is what you say, then it probably isn't.
