Save your money and go to the track to learn how to use 414hp before looking for more.
Now, if you're already a track junky, then X-pipe needs a tune to get rid of the Check Engine light. Too bad you're in Norcal, I'd consider selling mine since I want something with 200cpi. But if you were down here, Alpine could do most of the coding for $60!!!
Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
