PO hacked out the catalytic converters and from what I understand my 94" had 2 upstream O2 sensors on each pipe that led to each Cat. I found 95'+ setup with 2 manifold pipes into one single cat that should bolt right up to a 95'+ Muffler. My question is since there originally were 2 upstream 02 sensors and now only 1 upstream bung, could I splice the 2 leads to the one sensor? Any help is appreciated, and has anyone done this?
