I was just curious about how long our stock catalytic convertors last (year, mileage)? Who has had to replcae them here and what was your year /mileage?

 

The only time you should have to replace a cat is if there is something wrong with the car. A car that dosn't burn oil and is not running to rich should not have any cat problems. The cat is desighned to last as long as the car.
