Another mad idea of mine was - if Ace header can get just by itself most power gains possible for NA, and rest of exhaust is stock, i wonder if 2nd O2 sensor wire extender harness + bung for it cut after second stock cat in frontpipe can work, or due it being later down exhaust path/different temperatures and other possible differences, sensor placed there will have off-readings compared to what expected anyway and this also won't work?

unless you can duplicate the same reading from the o2 sensors as would be seen if the stock cat was in stock position on the stock tune then it probably going to trigger the cel P0420 eventually unless you disable cel, then your still stuck with the failed readyness test unless able to be forced reday by some code maniplation in tune as well
