well have 2013 mustang gt automatic,have sct tune-steeda cai-373 gears-roush axle back.car goes really good,never 1/4 miled yet.but was thinking about kooks headers x pipe catted mid pipes 1499.00 or stage 2 cams 1499.00 what would give me the most and which would cost more to install, what about relibility.what say you.dont want to make a radical race car want to drive alot and take on 2000 mile trips maybe.
