Favorite: The day I got blown Least: Under drive pullies - made my lights dim and no noticeable difference in power
Favorite: BBK hi-flow X-pipe (scared a woman at the supermarket once) or sequentials Least: Dynomax mufflers (they were on my 87 GT for all of about two days before Flows went on in their place)
Best: All that are not least favorites Least Favorites: Global West control arms, upr clutch adjuster and quadrant, Bullitt Springs, Engine killing crap X-M-P programmed autologic(and I paid for a diablo) chip
O I forgot that adjustable clutch cable I installed...worst...mod...ever. I broke about three of em before I went back to a stock for non-adjustable cable. USA ftw!
Fav: Steeda Cold Air Intake-improved sound and looks good Least Fav: Ford Bullitt Wheels-they fit good, look good, but weigh too much
