So, I called HP and they said that they will not be able to get ahold of any Hwarang headers for a few months. So, I have been considering the GT Header from Kspec. I was wondering what all of you guys think about that particular header and whether or not it is worth the money. I have read that people see good gains with it but gains worth $700? I already have all bolt-on mods possible (except for cams and headwork), so the header is the next step. I figure since I have all the intake and exhaust mods already that I would see a pretty damn good gain. Should I wait for the Hwarang or just go all out with the GT? Thanks for any input guys.
