I would save your money. A cold air intake isn't going to provide enough hp gain to be noticeable on an already 470hp vehicle. There just selling you snake oil. These things are flowing pretty well right from the factory. I don't believe replacing the exhaust is even going to gain you much other than making it louder. IMHO.
It almost seem like common sense. How can remove you air box that usually has outside airflow be less effective then adding a cone in the middle of your engine sucking hot engine air .
This is basically the conclusion I have come to...going to do a drop-in Amsoil Dry filter and leave the intake stock. It is not like my BWoody on my 08 that moved the IAT and sucked from low and far from the engine. Thank you for re-affirming :thumbsup:
