Pre-96, at least here in NC is safety inspection only, but that cat converter, muffler, all that stuff is a visual inspection. Plus on non-OBD-II vehicles, there is no O2 sensor after the cats, only before, so no CEL SHOULD be thrown.
On my old Bronco 2, of course the lovely ford engineers had two cats run in series, the PO of it had chopped the muffler off and the stuffing in the rear cat(metal mesh) was blocking the exit, as a quick fix to get her running well again, I got all that stuff out, and noticed that the front cat was clogged as it would glow red. Took a hammer drill and emptied it. With this all said, this was a TEMPORARY fix and should not , e permanent. The intentions were to put a High Flow cat on, but then I found my gem of a Cherokee and traded. Typically, car engineers design the car to run with a cat, removing one can harm the vehicle in the long run, not to mention its illegal.
