Have a 98 suburban 280 + on the chassis. The cat is plugged and I'm not finding any evidence of what caused it to fail. I always assumed that CATs are killed and they don't just die...
Is it possible that it died from age/milage? Or do I need to continue looking for what killed it?

Update.
I didn't really have much vehicle history other than knowing it was bought at an auction after being rear ended (used car dealer)
Without finding anything mechanical to kill the cat, I replaced it. With the old Cat off I took a look inside and it was broken up inside. It's been shipped.
