IIRC 7/8??? been awhile since I had to do one but I am pretty certain that's it

That is correct. I just put my WBO2 in a couple of weeks ago.

thanks i just want to make sure i have the right size wrench before I start
on my exhaust.

[Andy@Livernois]

make sure not to use the open end side, you will more then likely f it up..

I had some luck soaking the threaded connection with penetrant for 15 minutes before trying to break it loose...much easier.

7/8 oxygen sensor wrench works best and spray with Kroil for about 15 minutes before removal and to this day I have yet to have an issue with a damaged O2 sensor. Use anti seize on O2s when you install them also.

I believe this one would work better:

Get confirmation from Charlie first though, not my specialty...

A brake line style wrench would work too!
