I don't have a video, but currently my only mods are AP/ Cobb SF, and Cobb DP. Also its a WRX not an sti, but shouldn't change the sound to much(if any). I can tell you the intake is considered 'loud' as in you can hear it, but it sounds great not overly invasive but still there, mainly you just hear a whistle and the bov. With a stock exhaust and a DP, you can't tell a difference in sound unless you are driving around without the radio on, in which case it is a very quiet gurgle, but you really have to be paying attention to notice it to much. Hope that helps you some.
