If the engine is in good shape mechanically the cat should last the life of the car. There are a few exceptions.....Cars with known problems.
Seems on every automotive board I visit people don't change plugs or wires untill they are completly worn out and causing a misfire or misfire code.
But it was misfiring ocasionally long before the code poped up and IMO this kills Cats too.
When we sell a Cat. Inside the box is a piece of paper that says to fix the problem and not the symptom.
