Make sure you watch the vid all the way through as you can hear it more while he is driving.

That does sound cool!

Think the reason is the DV is now just before the intake manifold, so when the DV opens and vents to atmosphere theres still some pressure between the airfilter and DV, I suppose a good chunk of it goes out of the DV but the rest passes back through the turbo/filter. Getting right on my nerves to be honest as its a very annoying sound for a daily driver.

I do like the idea of having a loud one.

The 1 i posted recuric's which i think means it will not mess up your fuel and air ratios, and you still get the VTA when you want it.
Thats right yea?
