180K miles - do O2 sensors?

I googled it. Thought there was only 1 after the third cat

I thought that you had two cats with a sensor in front of and behind of each. Before the Y there is a cat on the left and a cat on the right. A sensor in front and a sensor in back. I looked at pics of all 3 available engines for your year. You did not supply that info so I had to do extra work. You will get my bill in the mail.

Is it worth doing just O2 sensors or should the cats be done also?

depends on how you drive, if you drive like a normal person they should last the life of the vehicle

did all 4 sensors on mine at 98k will do all 4 again at 198k currently at 165k
never had a 02 code on this vehicle yet, got a cat code and replaced both cat's at I think around 120k, then had to replace the left one again about 6 months ago because the material inside broke apart so it sounded like a mason jar with bolts in it getting juggled around.

Are bosch good sensors? I only see gm downstream sensors for my 09 5.3 on rockauto

You can use the Delphi sensors as well. I have never had a problem with them.
