Well I got bored today so I went down to my friends house and decided to take some vids to show my cobb CAI. First vid is with the windows up and the 2nd one is with the windows down(I just basically pulled a rolling start from a turn and guned it once I straightened out for 2 gears and shut down). Turned out pretty good.

Windows up:

I have a hks sport exhaust too but as you can see from the vids you can't hear it much(if at all).
