Greddy rs bov here. It was already on the ty when I bought her. No complaints. I did notice mine to be a little quieter than Jay's and not as high of a pitch. Try youtube for sound clips of diff bovs.

Older adjustabe HKS SSQV. Bleeds about a pound at 18 psi, about 1 1/2 at 22 psi. Great for scaring pedestrians, You can almost play it like an instrument with the throttle.
The bov's only job is to release pressurized air when the throttle body is closed while in boost. It's basic function is to extend turbo life by not letting the pressurized air back flow over the impeller blades which cause the impeller to change direction rapidly.
so you still keep the internal wesgate hooked up im going to look more on to this to install one in my truck since im just going to install a brand new turbo
