    A P0420 is a Catalytic Converter code, indicating that it is no longer working properly. A P01150 is a rear oxygen sensor code, this is the sensor that monitors the efficiency of the Catalytic Converter. I am stunned that it costs 1300 to fix an exhaust leak, usually that is a $50 welding job.

    How about a second opinion, because I don't that the dealership is explaining to you what your real problem is very clearly.

    here are some shops:
