update on exhaust issues... can anyone help?

I realize. No cats here. Most people that run no cats will tie the rears up. I guess my next step is to weld in bungs for the 02 and try another set of cheaters on those. From what I have understood though was that the wide band 02s are the front ones and the closed loop 02s are the rears to double check whats going on in front of them. Thats why on other cars you can get away with tying them up.
