Re: catalytic converters

Do you hear a knocking sound when driving over bumps or just at Idle?

No the catalytic converter will not give a knocking sound. But when you bang on the converter and you hear rattling inside the converter then the converter is breaking apart inside and would need to be replaced.

If you have any other questions please don't hesitate to ask. We are here to help the best we can.
