Cats are big $$. Before starting on a parts replacement, get the codes to verify what parts need to be replaced first. Will save you $$ in the long run. Cat's don't die usually unless they have seen a constant span of unburnt fuel. This is an EFI issue for the rich fuel ratio, get that fixed then see if the cats are still working.
