a 98 LS1 (which is the motor you would have if you are a TRANS AM and not a v6 firebird) has 2 cats built into the stock y-pipe, to eliminate them you would simply buy an "off-road y-pipe", this actually solves 2 issues, it eliminates the cats and gets rid if the "flattened" section of pipe.
bear in mind removing cats on a street car is illegal and can result in a multi-thousand dollar fine if you get busted by the emissions people or the cops (if they know what to look for), it will also increase the raspiness of the exhaust.
