What is the purpose and maintenance requirements of a catalytic converter?

The catalytic converter, an emission control device, needs occasional inspection for damage that could cause smog certification failure or low power. A backpressure test can identify a restricted converter. Replacement involves removing the exhaust system, installing a new converter with fresh gaskets and rubber hangers, and checking for leaks. For 4.0L V6 engines, the process includes replacing the exhaust Y-pipe, disconnecting the 02 sensor, and installing new gaskets and bolts.
