    Installed this 7 years ago and haven't seen P0420 since.....

    Google says it is around $180-225 in 'Merican Monies.

    10-4, autozone sells them so I am going to go this route.

    I have already contacted ZZperformance to return the straight pipe and they said that will be fine.

    So this weekend I install the walker and see what happens. If I still have an issue I may try switching to Acdelco O2 sensors as I am running Bosch right now and have read mix reviews on those.

    thanks for the tip

    If the emulator worked for several years and then the code showed up again, that means the emulator is dead btw. You could've just got a new one but like other said tuning it out is the best way
