Catalytic Converter: Testing and Inspection

Three-way Catalytic Convertor

If excessive exhaust system back pressure is suspected, remove the catalytic converter from the car, and make a visual inspection for plugging, melting,
or cracking of the catalyst.  Replace the catalytic converter if any of the visible area is damaged or plugged.
