Get the PCM tuned for higher octane fuel and matched to whatever other mods you want to do would be the cheapest/most bang for the $
Headers could help, but usually you won't see an increase from headers without doing the rest of the exhaust (high flow cat, preformance muffler..). And then you won't see a real boost from exhaust alone, you need Intake as well as better exhaust flow...so that puts you to a CAI...
And then there is the argument that even with a better intake and exhaust, you won't see much gain without modding to let the engine handle the better breathing...so you'll need the tune or better plugs/wires maybe..
Haha what a slippery slope.

Don't take this the wrong way (most everyone does though), but have you searched? These type of topics have been discussed in quite a few areas. Try a few different criteria, pretty much anything you can think of.
