i read in a car magazine that the ford gt picked up 50 hp by switching to borlas aftermarket exhaust system. i am not sure if that is headers + cat back or just cat back. whatever it was it looked sexy. the headers were long tubed and the whole deal looked hot. so now if you just swap the pullies out to get 16 lbs of boost and throw in some colder plugs and do a tune it should be good for 700 crank hp on 91 octane. assuming the stock engine makes 550 crank hp. :bowdown:
