I am getting the run around with this. I am trying to figure out which I will receive more benefits from. I am wanting to do the following upgrdes to my car. I have a 2008 GT/CS. I want to add shorty headers and a Borla or Bassani Axle-back exhaust; cold air intake with a throttle body and a tuner OR a ram air hood. I have been told that the CAI would just add a sound to my car and not really any performance upgrades. I was told if I wanted performance increase to add headers and I was looking at a Ram Air hood. PLEASE HELP!!! Should I forget about the CAI and just go with headers and the Ram Air Hood/ Heat Extractor Hood?
