Does anyone have this particular setup that includes the clutch and lightened flywheel? Does anyone know exactly how loud it is supposed to be over the stock setup?

We've installed 2-3 of them. They are louder, specifically at idle, and hi rpm decel. We did have one customer who came back after less than 1 year to swap in a different setup, although the noise wasn't the final deciding factor.

I personally love it, & if I had a TT, it'd have that lwfw/clutch on it. IMO the noise is minimal, & acceptable in regards to it's gains.
