what mods to buy with tax money??

ok guys im in iraq right now but got the green light from the wifey to buy some mods with some of the taxes money. id like to keep a limit at 500 bucks.
car is 03 GTP w/ plog,3" dp, magnaflow cat back,3.5, KN intake, overkill pcm, 180*, 104's ( 75 dry shot not installed) i was thinking SSAC headers or modded 1.9's w/ springs
i shouldnt be outflowing my TB correct? also thinking meziere EWP

suggestions for a soldier??

1.9's . My car really woke up with these.

either rockers or headers. both made a big diffrence. or buy HPtuners and have the ability to always tune your car and make it faster.

ssac's or hptuners or do the rockers and the headers and call it done

ssac headers for sure, they are nice pieces.

do the headers for sure, don't f with a plog. i know this!

buy a tuner and tune the crap out of your car. youll see the most gain from this.
