I think that the exhaust is a must, not as much for performance but pleasure. I have a corsa exhaust and love it. I also am running and air raid intake and a whipple supercharger. Like they said above, drive sensable and you will get the best you can get. I am around 13 mpg's. You will get used to the mileage. A few mpg's a gallon really isn't worth the money, do it for pleasure.
thanks
