What to do with rear o2's
 

I had them deleted and im about to put on some LTs and a true dual exhaust.... since there is no bungs for them, how do you suggest i deal with the connector?

leave the sensor plugged in and tie them up somewhere.

They are deleted no need to plug anything into them. Just make sure the wires are tied up and wont hit the exhaust or drag on anything. Mine arent even deleted yet and I dont have them hooked up because of installing LT's. Same goes for EGR and AIR inj crap. You will just get a code but it wont change the way it runs.

i just need to know if i unplug the rear o2s and just tie up the wires or what?? i dont think leaving exposed o2s is really all that good

you don't need them. but they're tuned out and I left them plugged in to keep the wire harness filling up with shit. you could just wrap up the harness really good.

What are you doing about primary O2's when the headers go in? Extensions?

Save the money and repin the PCM so the rear ports on the body harness side of the car read AS the fronts. Saves you from buying two new O2 sensors as well as long as yours are good...
