    hate to say it, but sounds like the catalytic converter may be the root of the problems, cause if its bad....it'll trigger those other codes.

    find a high flow cat from like summit racing i think there usually like $100 and probably another $50 for an install. a Factory cat will probably set you back a few, this is all what im taking from memory but yes unless you weld its a shops job.

    Before getting a new cat, make sure there are no exhaust leaks first! Then check your cats or have a shop check them to see if there bad or working propertly. But the last thing and most commen, Is your o2 sensors. They usually go bad first..

    Good news, after market cats are a quarter to a third the cost of a factory cat. The down side is they only last a couple of years compared to five to ten years.
