Keep checkin on Modern Performance, Psi-Fi Motorsports, Gravana Tuning, GM Performance Parts, etc. Also Check out our other site sponsors as well. I would recomend staying away from SCDyne, they have a header, but as far as I know there is ONLY ONE PERSON that has recieved everything they needed to install the header!!! I have not heard ONE POSITIVE thing from them YET!!! So just be wary of them, I dont want ya to go spendin your money on their header only to be greatly disappointed!!
