Exhaust, intake, intercooler etc all claims to increase hp but my personal experience tells me that they makes the car smoother but i dont feel any extra power. But when I installed the Cobb, the car felt a lot stronger even tho the hp increase from Cobb is fairly small percentage comparing to other mods. I hope it's safe... I'm only at stage one and reluctant to go any higher as I have the same concern
