All it does is monitor the efficiency of the cat. So, no it is not as critical since it doesn't affect the engine performance. Did you try it with a warm pipe?

Re: Welcome ar-guy!!!
Yea tried it as soon as I shut it off, no go, tried to heat it red hot, no go, waited for it to cool (hopefully to shrink) no go, so I gave up lol, the upstream ended up doing the same but I had to get that one changed so the dang thing would run. Ended up pulling the threads out with the sensor, had to get the tap and die set out....but its in and fixed and runs just have a CEL on the downstream, waiting on my oil pressure sensor to come in then we are back on the road! Then on to the MODS!!!.....hopefully
