Any thoughts would be helpful, thanks.

I understand your concern for the Y-pipe on Subarus, however, I would think if you drove the car up on ramps that it wouldn't be too hard.

It has made a difference on my 97OB. My milage had slipped a little (say 3 to 5%) and that has come back. As well, the carbon build up issue (just posted in the other thread) was being aggrivated by a drifting (failing) O2 in my opinion. I never had a CEL though. I only changed the front O2.

Took me around an hour because the bolts on the shield on the exhaust pipe were rusted and welded to the shield because of the heat. I had to cut them off to remove the heat shield. I replaced the front O2 sensor. It seems that the rear sensor should not take more than 1/2 hour.
Once that was off, it took me around 20 mins to uncrew the O2 sensor, put another one in and put everything back together.
So far, no CEL!

Measure the new one to find a suitable open wrench . I dont remember the exact size.
Just bend over the right fender and go at it. No need to go under, put the car on ramps on remove the heat shield. It's just under the right side inner cv boot. It took me 5 min to remove it, 10 to splice in the new pigtail (i bought a cheaper universal one) and 5 more to screw the new one in.
I usually take more time than most people here to do a particular job. So it must be very easy.
