Q: Car making noise.

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.
