so after having my borla exhaust installed yesterday the guy at the shop tells me my left o2 sensor is seized... there is no threading left it basically looked melted. do i need to replace it or can i go somewhere else to get it fixed?

Kind of an important distinction between seized and melted. Melted is indicative of a possibly more significant problem (lean condition) than a stuck O2 sensor. New one is the safe bet.
thanks bud, how about getting it replaced? should i go to dealer and pay labor?
To replace it you'll need to pull back the carpet along the center console, plug the new one in, fish the new wire thru the grommet in the floor, and then jack up the car, put it on stands, and install the sensor in the exhaust with the special socket tool.

should I replace both or just the bad one? rockauto suggests you do both.

Its recommended to replace both if one is malfunctioning. Since you're replacing due to stripped threads from exhaust changeover, you should be fine with just doing one.
The shop that was installing my borla couldn't get my o2 sensors off as well, said they were seized on there. So they ordered a couple o2 sensors to replace them. But they ended up not having to use them as after a lot of hard work the oe sensors finally came off.

the shop stuggled with the left one and came to find out it was seized. they repaired the threading on the exhaust and temporarily plugged it until i get a new sensor. No check engine light so far though.
If you live up north and unsure if they are seized/rusted could buy a couple of extra sensors to install on your new exhaust, and dont even try to remove the ones in the stock pipe. Then its just plug and play when you want to change back. Also avoid the risk of over twisting the O2 sensor wiring or cross threading during install
