its welded on, and you shouldny take it off you might get fined or even you might have your licnece suspended depending in which state you live in.... the cat cleans the exhaust gases from your engine, now if you want to change it wih a new one, you have to buy the original one and put it on( screws/ bolt it on) or you can take it to a muffler shop and have them weld on a new cat...
