say what you want. i know the injen made power. and while many had problems with it. i did not.
i put intake on by its self. then back to stock. exhaust by its self. then back to stock, pulleys by them self, then back to stock and so on. and i raced stock frs each time to determine what was better gains. so i know that it made good power. exhaust was about tripple the price and maybe half the power.
