I've noticed that when I shift at lower speeds, like under 40 mph, I hear a woosh sound when I shift. I don't know if maybe I am just hearing the clutch depress or slave cylinder working? I'm not sure, but I wanted to see if anyone else is experienced this? Its an '08 civic Si coupe

 

must be your turbo blowoff! ha its possibly just the air intake.

 

Yeah, I figured it could just be the intake, but I wasnt sure so I figured I'd see if anyone else has heard it too.

 

lulz...yes I've heard it. Intake.

Sounds sexy.
