Hey guys, whats up. I recently got a 2005 WRX. It's black and came with a decent pair of Motegi racing wheels. I love the look of the shark fin roof spoiler, and have already gotten that. I have also gotten a BBP N1 catback exhaust that rumbles beautifully. I have a little extra money to spend on more mods, and wanted to get an HKS blow off valve. What other mods do you think would add a kick to the car?
