A catalytic converter is one of the most expensive parts on your vehicle, and it rarely fails on its own — something else usually kills it. We find out what that was first, so you are not paying for the same part twice.

Common questions

Do I really need to fix my catalytic converter?

In practical terms, yes. The converter turns harmful exhaust gases into less harmful ones, and a failed one will keep a check engine light on and can block the exhaust enough to sap power and fuel economy. The more important point is why it failed — converters are usually killed by something upstream, such as a misfire, a bad oxygen sensor, or an engine burning oil or coolant. Replacing the converter without fixing that root cause tends to destroy the new one too, which is an expensive lesson. We diagnose the cause first.
