I just put headers on my car, will I be able to tell that much of a diffrence when I put on the icebox? I know they kinda work "hand-in-hand". Bad gas mileage....Oh it probally has to do with me and the lead foot. LOL.

I had just headers and then added the Icebox. My feeling is that the Icebox added all across the board. You will definitely feel the difference.

Intake and headers compliment each other very well. Later add exhaust. You will not notice much gain with exhaust, but the car will rev and accelerate a little smoother when combined with intake and headers.
