good long tube headers run over a grand, try looking for threads on the power gains of long tubes on the GT. I saw a gain of approximately 28rwHP with headers and o/r x pipe and new tune.

^i got JBA headers, JBA off road h pipe, JBA evolution exhaust and everything installed and tuned for $1700....just shop around and you should be able to pick up GOOD headers for around $700ish

Gears are GREAT, but you will spend more money to get them installed than you the parts is worth. I suggest you get on eBay and picked a used CAI, and a used Diablo or SCT tuner. Those two combined will open up your can nicely; plus you leave yourself the option of having the capacity to upload custom tunes onto your car after future mods. With these tuners, you can also recalibrate your computer for the gear swaps. Those parts (the CAI & tuner) are as good used as they are new, and you can save hundreds; I know I did. Headers are headers; longtubes do flow better. Long tube headers will require a custom tune, and that is extra money. The shorty headers do not require a tune. With $1000, you can get the CAI, tuner and a set of gears (installed) and have enough money left over to fill her up and get used to it. You may have enough left over to buy a set of headers, too. I paid $168 for my ceramic coated headers on eBay and they flow GREAT! That price included shipping, by the way.
