stock mileage on 96 or 97 dual cats?

might be a dumb question but what to everyone's general knowledge will the dual cats or well any lt1 cat really, get to mileage wise before failure starts happening? mine are fine but they are stock and i have 110,000 miles on them. muffler too, aftermarket or stock. thanks. i need peace of mind whatever it might mean lol

nvm found out anywhere up to 200,000

Can't really put a number on them, digging through old service records, the previous owner had one of the cats fail in the 60K range. Just one of those things. Cats do generally last for quite some time.
