Q: Car making noise.

asked by on

My car is making a noise. The catalytic converter needs to be changed.

The catalytic converter on the exhaust system would need replacement if it is clogged with debris, or broken apart inside, which would also clog the exhaust. I recommend that you have a mechanic, such as one from YourMechanic, come by and inspect the noise coming from your exhaust, to ensure that you get the correct problem fixed, before you spend the money on a replacement converter.
