O2 sensor removal?
Ok, so maybe my searching sucks but I'm pulling my hair out trying to figure out how to remove the sensors on the cats (2 on each side).
This is for my spec boxster but I assume they are the same on a 996.
I need to get this exhaust out today so I can call it a day and start doing real work
Thanks!

With cats removed from the car, attach the 02 removal tool to your breaker bar and twist. It should come undone pretty easily. If it is really stuck, someone probably left the anti-seize off. You might need to heat the connection with a torch and break it then.

Good point. I'll disconnect the wiring harness and then remove them once off the car.
BTW, what in the world is the O2 removal tool? Dealer thing?

Yup. Costs like 5 bucks at Harbor Freight or Northern Tool. Might be a little more at Autozone/PepBoys.
BTW, Dell, I ended up with Josh's car. 20,XXX on the clock. Delivered earlier this week, but I had some servicing done (oil, brake flush, filters, etc). Picking it up today.

O2 sensors are a standard size.. Autozone, etc have em. Since the space is super tight...Don't buy the deep socket looking one posted earlier you want a stubby looking thing that is slotted and has the 3/8 attachment point offset over to the side. See the link.

A long a$$ wobble extension seems to do the trick.
Since you are likely dropping the cats altogether, just unclip the harness and drop everything at once leaving the O2 sensors in place.

I had more of a problem getting the wire/lead snaked in and out more than getting the O2 sensor out.
I used an open-end wrench and it came right out. I may have been lucky though.
It is stainless steel, not cheap mild steel so minimal corrosion should be around the threads of the bung and sensor itself.

No luck at Northern Tool. I'll try autozone later. Just need to spend some time in air conditioning for a while. It's 90 and humid. Yuck.
I think that I am going to do the unclip method. I just need to make sure I know how to unclip them properly as I don't want to break the clips. It seems every damn clip in these cars is a new rubics cube every time
Suggestions on proper unclip procedure?
