Keep your factory O2. Add the wideband somewhere on the s-pipe. I put my wideband sensor on the header with it's own bung near the factory manifold sensor, when I had a header. Some people say it burns up the sensor running it too close to the exhaust ports. idk... I kept within AEM specs and it was fine. Are you turbo'd?

 

I just welded another bung just below the one already on my 2.5 in s pipe. that way its far enough away so it doesnt wear out

 

Aww I thought it replaced the factory one damn lol guess I'll have a shop install it. And I have the supercharger

I need a new o2 be4 the cat do you guys know any good ones that work with the tc

Our stock wideband (primary) 02 sensor is alot more resiliant to heat than the LSU 4.2 sensors (what most widebands use) Id recommend welding a bung at least 24" from the exhaust port (at the head). On turbo applications, keep it at least 12" from the outlet of the turbo (on the downpipe). As for the stock primary 02 sensor, you need to purchase a direct replacement, there is no generic one that will work. The Bosch part number is a 15960. Heres a link to one on Amazon, however I have seen them go cheaper on ebay/various other sites.

I also happened to run into this sensor, it basically says its a 15960 replacement from some unknown company. It should work, but how reliable it is, who knows. Its also only $65, so its up to you if you want to take a gamble.
