its a nj truck. cats arent required in my state. degutting a cat is not defrauding any one either. arent cats under federal jurisdiction .

midlant wrote no idea. maybe it depends on the year of manufacture. i know that here we have safety inspections and were allowed to switch to larger exhausts minus the cats its a nj truck. cats arent required in my state. degutting a cat is not defrauding any one either. incorrect statement sir. cats are required by federal law on all vehicles produced after the mid 70s or these about iirc. just because a certain state az in places here for example do not conduct emissions testing does not allow one to legally remove or otherwise alter your cats. .
