4:30pm To heck with it - Decided to run the car with three of the four sensors replaced. The SES light is out (hopefully not burned out) and the car is running smooth again at speed and at idle. I think I've got it taken care of for now. Next time I go in for a oil change I'll ask the shop for advice on the remaining one.
Here's a shot of the three I replaced. Pretty rough shape.
Also, I found out that the specialty socket I ordered with the sensors was basically useless. There's no room to use it anywhere except for the passenger side pre-CAT sensor, and that one was the easiest one to get to. I needed to use a 7/8" wrench on the rest.

Just to let everyone know, performing any welding on the exhaust, without removing the O2's will RUIN an O2 Sensor. Dog, your sensors were fried by the welding that was performed. Not ironic that they went out right after they welded your exhaust. Sorry this happened, but had you pulled out the O2 Sensors prior to the welding, the O2's would still be working....

this is one of the best reasons for LT's. No more issues in getting the O2 sensors. I'm surprised the post cat O@ sensor hasn't tripped the CEL yet. Unless you tuned them out?
IIRC I broke all the harness holders so I replaced them with zip ties. I also had to reroute them away from the headers too.
Yeah your O2's were fried. Had the same thing happen when the shop welded a new bung on my headers.
