okay, well Im selling my cat, its up on ebay right now, but now that Im looking for a different one I honestly have no idea which one I need. Im looking at all the options, and I dont even know if I had the right one to begin with. Im seeing ones with air/no-air, 1 boss/dual boss then theres oval universals and short oval universal... I think I just need a universal with dual O2s dont I? or is it just 1.. I honestly cant remember right now. TIA.

I think your right (if you needed the air you'd have a tube going down to yours now) most of the aftermarket ones are very similar. I have used dynomax ones with good luck (amazing as it sounds I don't mind their cats) basically stick to a name brand and you'll be fine, don't bother with the cheap off brands as they actually flow worse than stock

I know Im getting a carsound for sure... Do I need 2 o2s or just 1? I think I need 2....?

You don't need any o2s on the cat. There are 2 sensors (one in each header down towards the collectors) and one POST cat sensor in the S-pipe of your exhaust.

i thought there was 1 O2 sensor on the cat but im not sure it might be a different type of sensor

Nope, no sensors in the cat, one after the cat.

If the S-pipe doesnt have an O2 bung, can I get a cat with a rear O2? Cant remember if mine does or not. Do I need this?
