P0420 or P0430 is always a bad cat. O2 sensors throw different codes. If you want to just keep the light out, you can buy spacers to space out the rear O2 sensors, which will trick the computer into thinking the cat is working, but eventually the cats will have to be replaced.

No problem, I didn’t even notice that. I just went and deleted the other one. Thanks for letting me know about it.
