Hi there. Thanks for contacting us today. There are a few things that can cause a catalytic converter to wear prematurely. The most common is excessive use of aftermarket fuel additives or using either poor quality or leaded gasoline (racing gas). A failure of O2 sensors can also cause excessive carbon deposits from the exhaust. If an aftermarket exhaust has been added, this can also cause them to wear, as can using aftermarket replacement catalytic converters.
