The Corvettes are always closed until they hit a certain RPM (3000+/-?) If you tell me that this is not accurate, it will make me very happy!

BTW, I just received my clutch reservoir from you guys. Now I just need my car to be built so I can install it!

From what I have found, you can close the valves even at idle. I have not had the chance to play with one in person yet, but check out this Youtube video.

BTW, Thank you for your order. We appreciate your business and support!

It is loud during cold startup with NPP. Shakes the walls of my garage! Hot idle is low burble. Love it. If your neighbors complain when a "normal" Tahoe is started, they should have bought in a different neighborhood. It won't be that match quieter with the flaps closed is my prediction during warmup.
