Well... one thing for sure was that my bank1 sensor 2 was barely long enough to reach the front of the cats and the other o2 reached the bung I welded but I still needed few more inches to turn it around and screw it in.

Anyone knows if we can buy post/down stream O2s with 4-5 feet of wire? this way we won't have to cut them? Then again if a tune can fix the problem then I rather put the $$ towards the tune.

How much is a tune that can fix that problem now days?
