I currently have some long tube 1 3/4 hooker headers with a magnaflow cat back and a cut out before the axels. Changing it out for some lpp headers I just purchased with a borla exhaust. Going to run the cutout where the plates are suppose to be. Gong to get a meth kit to run a little cooler iats. Any guesses on how much power I will gain with these upgrades. I'm currently at 550 HP 530 tq running 9 lbs of boost and 91 octane.
