I agree that after market BOV'S make noise, but like on my engine CX25 GTi Turbo2, the factory recirculating type caused disrupted airflow to the intake. The standard airflow meter is Bosch with the flapper door and when testing the standard dump valve, you could actually see the door being pushed closed for a split second. With a twin piston dump to atmosphere this has been stopped.
However, the new build engine is having a complete new fuel management system, so this won't be a problem.
As for Wiki, it proves my point that more performance can be had by giving the waste gate it's own pipe and I still don't see why, with a good silencer this can't be done and still be quiet.
