Thanks for the suggestions Tennishoes. My pockets aren't deep enough to get all those parts at one time. Which of the suggestions you provided would be the most reasonable cost effective option to start off with?

Cold air intake, underdrive pulleys, headers, cat back exhaust, ECU tuner are the normal mods.

Total waste of money. Don't mod the the V6 save your money until you can afford the V8 mustang.OR DO all the mods gain a few horsepower.
