Catalytic convertor is part of the exhaust and expensive to replace. A cat code rarely indicated replacement. It is one of your sensor indicating a lean or rich condition caused by other factors of your engine. such as a misfire or lean condition. Best to get it diagnosed by a pro before replacing parts you don't need.

I see autozone scanned your codes and what is listed is the worst case scenario. Code P0430 may mean that one or more things, the catalytic converter is no longer functioning properly, an oxygen sensor is not reading (functioning) properly or there is an exhaust leak. Have your local garage diagnose it for you. Read more at: http://www.obd-codes.com/p0430 Copyright OBD-Codes.com

Could a possible electrical fuse make that code pop up!? There are no engine miss fires, the exhaust is not loud, the engine doesn't leak any fluids, the car drives really smooth actually.

No fuse. Are you going to have your garage diagnose the issue or are you going to start replacing parts yourself?

I'm going to have someone diagnose it and probably do some work myself. I can't do the catalytic converter myself but spark plugs I can. Things I don't have to weld and/or use a lift for.
