YOu answered your own question.

Which sensor? The one on the o2 sensor housing or the one after the cat?

more then likely before, thats the one that changes the air/fuel ratio and plus you will prob get better gas miliage after you change it.

Here's a question, what is the best kind of o2 sensor to get? Is it going to be hard to install a universal? I know NTK has OE specific and universal ones. An OE goes for about $65-80 depending on where I get it from. The Universals are as low as $45. Any ideas?

stick with the OEM.

The one after your cat simply tells your computer that the cat is working, it's the one in the o2 housing on your turbo.

you're actually downgrading by paying more for other brands. are you still on the stock turbo? I can't figure out why you're not passing...
