Does places like Oreilys or Napa carry 02 sensors for 04+ GTP's? Even after soaking my 02 in pb blaster and letting it sit over night it won't budge. Tried for hours getting it off and just going to give in and get a new one. I will need this part soon though so I need to get it tomorrow if possible (why I'm wanting to go local with my purchase).

yes. I forget which brand people say to avoid, I want to say it's Bosch (even though that's the kind I'm using,  )

You need to heat it up to get it out.
Go with a new AC Delco o2.

Here's the AC Delco numbers, if you want to find them locally:
Front O2 Sensor: 213-1553
Rear O2 Sensor: 213-1641
Two places that carry AC Delco parts in your area:
Advance Stores Inc #6097
510 S Duff Ave
Ames, IA
(515) 233-1450
Central Auto Supply
1920 E Lincoln Way
Ames, IA
(515) 233-0071
Hope that helps!

450 ft/lb 1/2" drive impact + (2) 1/2" drive extensions + 1/2" swivel socket = win.

LOL, mine came right out when I did it, no heat or cheater bar required. Took MAYBE 100 ft/lb.

Can you run just a bolt in where the 02 goes?..or is the 02 a must? If it only throws an SES light I'm not concerned about that. Any thoughts?

The o2 is a must.

Front O2 is a must. Rear doesn't matter. I disabled the rear O2 codes in my PCM and I don't run it anymore. Front one is essential for rich/lean adjustments.

One caveat with rear o2's, certain years will attempt to run a diagnostic continuously that dumps fuel if you don't have it in place. It is watching for extra fuel to cause the rear o2 to follow rich. I think it's 01+ that are affected. Not sure if the 04+ fall in this category as well, I will inquire.

I'll go purchase a bosch and play it safe. I can get one and it won't be too big of a deal.

Ended up not needing an 02 as the ZZP 3" Downpipe's that are catless do not come with them. I got the downpipe on successfully. Good times:D
My 3.6 MPS came as well today.

The only thing the rear o2 does is read the cat. If there is no cat, the purpose of having the rear o2 no longer exist. Get a plug in spoof or have the codes removed from the PCM
