90-91 model mods/tips needed.
I have a stock 91, 97,000 miles, auto, 259 gears. I am looking for mods and performance tips to get HP. I have a EGR code that comes and goes any suggestion on that. No smog control on where I live.

Long tube headers will make your engine breath better. Heads and cam will make it breath deaper, combine the headers and head/cam and you have a nice setup. After you go with all of that a set of gears will really rip you out of the seat.

i love the vanderzanden engineering kit, basically is long tube headers, a true dual 2-1/2" pipe set up, dynomax mufflers and chrome LT-1 style tips, retail is $699 but sometimes they pop up on ebay for $100-150 less. search words should be c4 exhaust

I reccomend the major mods in my sig. I'm really happy with the power it produces. It maintained great drivability and without popping the hood you would never know it wasn't stock :D I plan on doing exhaust over the winter....i think after the exhaust I will hit mit 12's. If I were you I would ditch those 2:59's and get a looser convertor first.
