if its a OBDI car, if yu take it to the emissions place they will test you exhust, if it doesnt pass, you need a cat. I think OBD II will tell you if it thinks a CAT is bad because it has OS sensors Aft the cats, Im not sure about this because I never own that OBDII junk (jk). Both systems will tell if the o2 Sensors are bad but you will need to scan the computer to find the code.

you know many states dont enve require CATs or emissions screening, Like Flordia (Proud to say I have only own One CAT in my life), just cut those hummers off if it OBDI
