Ok, after a bit of research, I think I should go with the AEM21-8111 cold air intake and a custom tune with XCal2. Does anyone have this setup, and perhaps even a before/after dyno?? I went to a local shop and this is the direction they were steering me. They also said after this I really should only need a good exhaust and that would be about it. He did not recommend headers, that it would not be worth the investment, or underdrive pully, (couple Hp gain at best). I think it is good he is not trying to sell me a bunch of stuff that wont help my car's performance, but is he right?????

I too have heard that headers are not worth it for HP, however I have heard great stories of headers combined with a true dual H pipe exhaust make our 6's sound meannnnnn!

I dig my jba headers... revs quicker and harder... HUGE improvement in sound... a very noticeable bump in hp/tq

Well hamidlmt actually has them installed, so I would take his word for it.
