I don't mean to harp on this too much, but I have been asked this question to the point of me having to pull out a factory "diverter valve" and a "blow off valve" to prove to a friend that they were literally the exact same.
Nice! Thanks for the info. Have you switched yours out to an aftermarket one? I'm thinking about switching it out but I'm afraid i'd lose a fair amount of boost because the pressure isnt recirculated, if i get a BOV. Was just really interested in the sound w/o losing functionality.
Honestly, your best bet is just to get an intake with an open element filter. It will increase the sound of both the turbo and diverter valve. On top of all of that, you'll have a few extra horses from swapping out the factory intake which are made to muffle sound from factory.
