ready to pull trigger on cai and headers
So tomorrow is the big day for the 08. My question, and guess I need some reassurance, is: will the car run fine with the CAI and headers but no tune (seeing I'm not ready to drop the engine warranty)?
I know the pitfalls of hydrolocking with the CAI and am willing to take the risk but do any codes ever come up from adding these 2 items?

Of course it will...High flow cats will often (usually) throw a code unless tuned around or out..

I have a buddy that just did LT headers and high flow cats and he got the extended O2 cables and his car throws no codes. He does not have a tune either. The key is making sure you connect the rear 02 sensors or buy 02 SIMS.

Hooking your rear 02s up with the high flow cats will still most likely result in codes and this is one of the reasons why many people, even those with high flow cats, have the rear 02s turned off in the tune.
If someone is suggesting 02 sims, have them give some suggestions as to where they can be purchased.
One of the companies who was making them got hit with severe fines and penalties.

You will almost certainly throw codes at some point with the high flow cats you will be using with the headers.

CEL = check engine light.
You'll get one with headers and CAI, most likely from the O2 sensors- either the rear ones, or the front ones not coming up to temp quickly enough.
Sounds like you've decided against the headers and CAI. I'm guessing you don't know what you're missing. Have you ridden in a car with headers/CAI and tune?
It's mmmm-mmmmmm good.
