You should still do headers (a good equal length, **** the sound, power is what counts) as that will give you your largest bolt on performance gain. Then, go crazy with handling mods.
dude, you are out of your mind. I agree about upgrading the suspension but cams headers and a tune will not put a 2010 2.5i anywhere near a 2010 WRX or an 09, 8 7 6... you get the point. Do you realize a new WRX has 265 HP and is faster then the 2008 or so STi?
