The trusty 2004 SE/SC with 141K on the clock has presented me with a conundrum. It is throwing a P0420 code, catalyst inefficiency on bank one. Took it to the dealership today and they have confirmed that the O2 sensors are working correctly, so the cat itself is the source of the code. Having the dealer replace it is not an option as they want $1100 for the job, and almost $700 just for the part. Not in this century....
A local exhaust shop has told me that they can replace it with a "universal" cat for about $250. Probably doable, but am I borrowing trouble going this route?
Third option would be to replace it myself (Magnaflow has bolt in number for $219) but the ones I've seen are listed as excluding the supercharged model. I can't see as how the exhaust is any different on the S/C over the normal V6 but maybe I'm missing something.
Finally, I'm tempted to just eliminate it altogether but I'd need to spoof the O2 sensors to do that and I'm not sure how to go about that operation.
Any other ideas or advice?
