TurboSmart 50/50 vs symposer port BOV?

[djryan2000]

I currently have the Cobb intake on my car and want louder turbo sounds; more specifically, a louder “psssh” sound. I’ve eliminated the spacers from poor quality reviews. I’m currently between the TurboSmart 50/50 BOV, TurboSmart symport port BOV, and the Boomba Racing 50/50 BOV. I just want to be able to hear it more with the windows up while driving - even with the windows down the stock one isn’t that loud.

could anyone explain to me the difference between these products?

I went with the symposer bov. I have only heard the 50/50 in youtube vids but mostly I did symposer for ease of maintenance/adjustment. The location and workability in the factory mounting spot was infuriating to deal with. I can say the symposer bov has more of a whoosh when opening at lower rpm but gives that cool higher pitch chirp when on the throttle harder. I am on stock airbox with just a panel filter, some of those aftermarket filter set ups amplify those sounds from my research.
