I just had to replace the cat on my 1990 E350-RV with 460 engine. I had an overheat last year and I believe this cooked the PIP, Engine temp sensor, and the cat.
You might find an old-school shop that will straight-pipe your cat (cat delete), or you can do it yourself. With that old an RV as was pointed out you won't have an O2 sensor downstream of the CAT so no check engine lights to worry about. If you live in a state that doesn't do emissions you can get away with it.
I could not get my cat off by myself so had to have a shop to it, so I had to have a cat put in.
It would be rare to find a shop. Fines are pretty bad if they get caught.
OP, look around on the web for a “test pipe”. They are made so you can take the cat out and put the test pipe in to see if the cat is the problem. Wink wink. Nod nod. Say no more!
