I had nothing connected for a few weeks... Just ducked taped my connectors so no dirt got in them...
All you get is a CEL... No biggie...
rear O2's = useless.
front O2's = important.

I would recomend getting 02 sims, they dont cost that much, less than $100, I don't remember exactly. I have a catted Y but after 3k miles I started to throw a code because the high flow cats just stopped working....
but who cares? It makes the car sound like it is faster than it really is. LOL. You will get sick of it after a while though but have fun for a while.
