Well you'll have an upstream O2 sensor and a down stream. On a California car there will also be a third one after the secondary cat. You can see on the link you provided there it has 2 holes for sensors. The third will be mid car in the center pipe.
I looked under the hood for Emissions sticker for California or Federal but my luck no stickers anymore. You can see where they was but gone now. I do have the window sticker of the car when we got it new and it says catalytc converter 50 state emissions control system on it but dont know what that means.

I will check for the 3rd sensor tomorrow. Way to cold and dark out right now. Thank you again for your info. This is a learning experience for me.
You could really do the install yourself with some basic hand tools as long as you don't live in a northern salt state where it's all rust. I have a 2002 apart down to the crank/pistons right now in one of my bays. It had a bad converter, luckily though it blew out the bottom not the top. Head gasket just happened to go too. Vehicle has 241k miles on it and the timing components still look good. Good thing though as the lady wont pay to have them replaced while I have the hole thing tore apart.
Yea I think your right about doing it myself. Having trouble finding a California emissions one to buy right now without paying a arm and a leg. Thats all I can find on eBay is non California. That Rock Auto link I ask you about I'm pretty sure it was non California also. I live in Arkansas.
I will get you a list of needed tools tomorrow when I put this one back together. Just had a brainstorm, give me your VIN and I can run it on my NNANET and tell you if it's Cali.

Well I don't see a 3rd O2 sensor nor do I see a second one on bottom of the Manifold cat. As best as I can tell there is only 1 sensor up at top of first converter easily accessed by just by raising the hood. All the cats I see to order OEM or not has a O2 location before and after the Cat that's connected to the manifold. So what if it only has one? What is the second spot for on the lower end of the Manifold/Converter?
I promise you there is a second after the cat. Likely a heat shield is inhibiting your view. The first one reads the oxygen content when the exhaust leaves the combustion chamber, the one after the cat reads it again to make sure the cat is functioning properly. It has to have at least 2 per bank. You'll need a 14mm, 12mm, and 10mm for the job. I suggest 1/2" drive deep well with a 3" extension to remove the manifold bolts. The Alternator has to come off before that manifold will. It's held in by 2 14mm bolts. One is very long and you'll need to remove the Coolant overflow, and IPDM "fuse box" to get it out completely. The heat shield is all 10mm bolts, don't worry if they break you can replace them with M6x1.00 bolts 1/2" long. The new manifold will likely not line up perfect with the heat shield, even factory ones don't. Unhook the battery, you need to unhook the alternator and if you arc the main lead off of it you'll ground out the circuit and make a light show. If you need anything else lmk.
Cool man. Thanks again for all the info. My X bro in law is a mechanic at a local automotive shop. They have a nice scan tool and all the proper tools to do it with and hes gonna help me do it. I appreciate you taking all the time to help me out. I found that converter I showed you off ebay on the people main website and its cheaper on there I guess cause of no ebay fees. Check it out its $229 free shipping. Thanks again!!!
Ok I will. Gonna talk to my bro and maybe get this ordered tonight. Be next week before I can tackle it. I gotta work fri,sat,sun 12hr shifts. Thanks!!
Well I got it done total project cost $229. My X bro in law helped me and didn't charge me a dime. Took a 1hr 1/2 from time we raised the hood till we shut it. All went well all bolts come out easy and everything went back in and lined up without any hassles. The bolt at bottom of converter that screws in side of the tranny housing or block was busted off. The bracket itself wasn't broke the case hole that the bolt screws into was busted off. I'm gonna include pics so you can see. I'm gonna see if someone can weld this back on so it will be secure at the bottom cause I know it needs to be. The code cleared itself a few seconds after we started the car. All is good now except the bottom bracket. I thank you again for your help. This saved me a ton of money.
