I am still deciding if I should buy a CAI/Tune for the car because I may save up more money supercharge my car at East Coast Supercharge. I got a modification itch bug on my butt now. After researching, headers/mid pipe with cats are only mod that I can do now until I make N/A vs FI decision in next few months

How much horsepower AR headers 7/8 or 3/4 and high flow cats would help a bone stock z06 to gain? I know it will lose some weight and how many lbs? .
