I didn't Install my cutouts for anything performance related. I've read some people have gained 5-10 hp a friend of mine actually gained like 8hp but apparently the person above me lost power. I have heard that cutouts can cause false knock but I just installed them for the sound they sound badass when you are cammed and WOT it's awesome
