I'd be interested in knowing how it looks throughout the rev range. Idle is rarely an issue for me. Cruising is where it becomes a problem. A plot of dB, frequency and engine RPM would be very nice to see!

Either way, I'd expect the WG to be sufficient for my run-of-the-mill setup.
Comparing a suitcase muffler of unknown internal design (Q300) vs. two tiny 5" cans on the Nameless? I think I'd guess that the Nameless would flow better. The pipes may be smaller with the Nameless setup, but I'd have to guess that the muffler is a much larger restriction.

And as for how it actually performs; if you see overboost with one and not the other, then I would hypothesize that the one that is overboosting is flowing better. A tune may be able to fix it.

The wastegate being "enough" for your setup is kind of backwards. The wastegate's job is to hold back the turbo from spinning out of control. The more "tame" your setup (ie. less boost), the harder the wastegate has to work. At 20psi your tiny internal wastegate is being required to flow much more air than my large 44mm EWG needs to flow (at 27psi).

Sorry for the (now) official thread jack, it's been a slow day at work.
Oh well. I don't mind. I had a bunch of stuff to post, but I don't want to interrupt this discussion...
