When cat starts to deteriorate you should be able to tell and even start
getting some check engine signals. It may last until the bottom does
fall out so I would wait. Same with the muffler. You will know when
that needs replacing as well. These are things you don't need to do
until their time is up unless it brings you peace of mind. If you lie
awake at night worrying about them then by all means replace them.
Check the price of a cat and that may make the decision for you.
IMO, those things are not going to leave you stranded in the middle of the
night and they give warning, so why spend the money now?
I've had exhaust systems last over 15 years so I'd not rush. You'd really
be PO'd if you put a new exhaust on the car and the bottom did fall out.
