    OBDII code P0430... bad cat?

    Hey guys, question:

    I had a SES start showing a couple weeks back, bought a scanner which pulled code P0430 for "low catalytic efficiency bank 2." Should I assume the cat is dying on the passenger side? Could my O2 sensors be failing? The car has 91000 miles so it is about time for a cat to die... Maybe it is time to buy headers


    Any advice is much appreciated, thanks

    I disabled my rear O2s using HPTuner Pro when this code was thrown at just 55,000 miles! Its not a huge concern, reset it and see how long it takes for it to come back again.

    If you can do LTs, get on it! I just upgraded to a set of Kooks and their ORY and the car sounds mean as hell. Can't wait to get the other upgrades wrapped up so I can take the car out for a spin.
