From what I have read so far is CAI equals more noise upfront and modified exhaust equals more or different noise out back. You would be better off contacting one of the many performance tune companies that get good reviews on the forum and work on a total package. In the end, it's your money spend it on what makes you happy.

or a poor tune. Let's face it, bolt ons on a n/a motor aren't going to net you huge hp gains, but those are crappy results. Even if your 2nd dyno run was in an enclosed trailer with no ventilation, on a 100 degree day, after driving 50miles.
