Since you upgraded to wide band oxygen sensors with the 2006 motor you'll be seeing an SES light if you go the headers route. The only real solution to that problem is an Uprev tune to delete the secondary codes. Alternative is Racingline high flow cats and you can buy the y pipe from him as well. Not as good as headers for performance but still an awesome kick in your cars a**. On top of that you'll also pass emissions if that matters where you live. I personally don't like CAI's but they're all basically the same. I've said this a hundred times, spend the extra money for the best filter available. If you want the best performance out of the car you should look into doing a custom 3" exhaust.
