first mustang

[wade73]

well after 1 year of searching and 14 years of wishing, i finally bought my first mustang. 1998 gt, 22K miles, black/black, 5 speed, 16 inch "5 star pony" wheels, stock everything (about to change). bought it from the proverbial old man that only drove it on sundays, and kept it garaged the rest of the time. (he actually lives right down the street from me) it will be a daily driver, so i need some advice. i understand that stock, it came with 215 hp. i would like to get in the 290-300 hp range, which shouldnt be all that hard. my best guess would be underdrive pulleys, k&n air filter, cat back exhaust from borla, and possibly a chip. the only other mod i care to make is possibly with the suspension (lower it about 1", firmer springs), and maybe wheels.

my question is: what chip/exhaust/underdrive pulley manufacturers would you recommend, and will that get me to the horsepower range i want? and what spring manufacturer would you go with?

thanks guys and gals.

p.s.: x pipe or h pipe? whats are the benefits of each? i ask alot of questions cuz i dont want to screw up!
