Questions about the DPs, STFA already and is still confused. TIA.
1) I know there are 4 O2 sensors on our cars. Are the 2 front O2s located right behind the turbos? These are the ones that are hard to replace, corret? The 2 in the rear, are they before the cats or after the cats?
2) In case of piggie pipes, which 2 sensors are you re-locating? The 2 sensors right after the turbo or the 2 sensors in the back?
Thank you for your help.

would piggie DPs with test pipes (no cats or precats) and stock-cat back for now be bad for the car?
