Questions people ask before calling

How do I know the cat is bad?

A rattling noise underneath, a sulfur smell, loss of power, or a P0420-style code. A shop should test before replacing.

Were catalytic converters getting stolen?

Yes — thieves target them for the metal. If yours is missing, you'll hear a roar and need a replacement plus maybe a heat shield.

Is a used converter OK?

Some shops install used or aftermarket units; check warranty and local emissions rules before you choose.
