I have a 1990 GT, everything stock except for flowmasters at the moment. Going to buy a 3.73 gear and some headers and possibly an H-pipe. I just need some opinions on what the best headers and H-pipes are for the money. I'm on a tight budget and trying to stretch the money out as far as it will go. Any other suggestions on some quick bolt-ons that will help performance in addition to the gears/headers?

I've had MAC shorties on for a couple years with no troubles.......inexpensive and easy to install..... the gears are gonna be the best bang for the buck. And a short throw shifter is a good investment also.
