    Joe, the P10/P12 I4/I5/I6s only have 1 bank, bank 2 honestly shouldnt even be a valid set of PIDs.

    GB, not sure why this is happening, I like the possibility of the rear O2 hitting the heatshield like Joe suggested.

    So by putting the sensor near the heatshield would benefit the sensor? I wont think that the sensor near the trans will generate a lot of heat towards the sensor.

    Well just by looking at the old cat and picture the sensor seems to be near the same direction compare with the new header pipe but its just a little closer to the cat below.




    I just change both sensors a few months ago. I hope i wouldn't need another rear sensor...but ill take a look

    Only Stainless Works makes headers for the I6 that fit a TrailBlazer/Envoy.
