Looking at getting an 09 G8GT. I want to do the D.O.D. delete and get a cam for it. Something that chops and is still able to be daily driven. I wanted to do the intake headers and exhaust as well but after going through everything I want to do, it seems to be kinda pricey for what I'm trying to spend at this very moment. So I would like to go one way or the other first preferably dod delete and cam first. Could I do the dod delete and cam first without adding aftermarket headers or exhaust? Also when doing the dod delete to remove the dod pressure relief valve can I use a regular non dod oil pan from an ls2? Lastly what all needs to be done if I were to only dod/cam it? What cam specs would make enough difference in sound and hp gain while keeping things stock such as the stall converter and throttle body as the car will be entirely stock before this.
