Just sold my winter project 86 mustang gt. Bought a 03 gt with no cats, X-pipe, dual Flowmasters and cold air intake. Was wondering what you guys think are good bolt on upgrades. Not doing heads or anything. I plan on doing 373 gears, possibly headers, MAF, 70mm throttle body and plenum. Underdrive pulleys. What order should I do these in as far as best bang for your buck?? This is not my daily driver, also I will not be taking it to drag, just here and there cruise nights and banging gears around town. Thanks for any input
