^ Like he stated...unless it is catless, the exhuast should not be causing the code. If it is a catless exhuast the only plug and play tune that would get rid of the code would be from one of the factory Staged PCM's as they don't read the downstream sensor. (probably the only benefit you get from a Stage 1 ECU, as a predator would net you the same or better performance gains.) But, you can't even just slap one in your car because it would need to be re-flased to your car. Also, you can't get them anymore, unless you are buying used off the forums or ebay.
