As you've probably already noticed, all the CAI and Headers did for you was to make more noise. If you want a meaningful bump in power, think forced induction (i.e. Turbocharging or Supercharging). Oh, one more thing, think MONEY too.

Go with the basic. Open up the exhaust up 2 1/4inch . You dont need a loud muffler just better flow cold intake and headers does help. but we dont notice it much sense it is not big gain. but you go with a vtec head also i am sure you can find that info here. If not go cheap a spray nos this subject has been touched in any car forum sense the 90's. Its more about of how much you want to spend.
