AP1 all the way. I have an 03 and my manager has an 06. To me, driving mine is a bit more fun than his. As soon as you hit vtec in the AP2, your pretty much already shifting. And going to 9k is a bit more fun

Plus for some reason, my stock radio/speakers sounds better than my friend's 01, and my manager's 06, both when they had stock headunits, and after they changed to aftermarket
