intake wise:
get a CAI, manufactor? just search around every1 has personal view on what to get. me i went and got an AEM v1 CAI. for show reasons at first then preformance (after dyno'ing) later

exhaust wise:
get a full cat back from one of the bigger manufactors cuz fitment and preformance come into play more than saving a few dollars.. personally i went custom for my exhaust and was happy with it but thinking of getting another kit cuz my piping wasnt layed out properly and is getting messed up since my ride is so low.. looking into greddy or Apexi many on this board have both of them
