The life of your catalytic converter depends on the condition of the engine and the fuel you're using. If the fuel has the wrong additives, the catalytic converter can become plugged up. If the engine burns oil the oil vapor will build up on the catalytic converter and it can become plugged. Otherwise, if the catalytic converter isn't plugged, don't replace it.
