im not doubting it does add, but i cant see youd get a gain of 30-35 HP from only a tuner, filter, and catback exhaust.
the dyno chart on 5stars site shows a 16HP gain. no way are you getting another 14-19 HP from catback and filter.
Why not? I get an extra 5hp for every cool sticker or decal I add *****!!!
