Best Practices

Catalytic converters are vehicle-specific parts. We recommend using a high quality new part, which is required by emissions control programs in many states.

Common Symptoms

A failing catalytic converter can cause a Mercedes-Benz R500 to fail emissions tests and the Check Engine Light to illuminate. The exhaust might have an unusual smell.

A "restricted" catalytic converter can result in a loss of engine power.

Common Misdiagnoses

It is very important to have the shop identify why the catalytic converter failed. Failure is almost always due to another problem, which if not resolved, will quickly ruin a new catalytic converter.
