    Front o2 sensors

    Im looking at this header and y pipe
    It does not have the bungs for the front o2 sensors. I want to have the rear o2 sensors tuned out. Would i be able to have the front o2 sensors tuned out as well? Would there be any chance of me hurting something? I will be removing the EGR and AIR so I believe i would be able to have these codes tuned out as well correct? And while I have these on the car would it be safe to drive with the codes still on? Thanks for any help

    your AIR, EGR, and rear o2s can be deleted and codes tuned out (all of these are for emmisions)
    you need to keep the front o2s so your computer knows how much fuel to give thr engine. if the headers don't have o2 provisions, you need o2 bungs welded in to mount the front ones

    those look to have bungs to me. Look at that very last picture and you can see the bung on that header closest to the camera just about 2"-3" to the left of the sun glare.
