Re: Cheating o2 sensors is it possible?
That might work, I had an 02 Z72 that I used for boggin and put straight pipe off the manifolds, the front o2's I put back but the back ones I tystrapped to the frame and that worked, I don't think the rear do much than tell the computer if to much carbon is getting past the cats so if the are outside the exhausts path all should be good.
