I have a gfb deceptor blow off valve/ diverted valve. It's adjustable so u can decide how much you want recirculated and how much to blow off into atmosphere for the swoosh sound. Also is adjustable for how much pressure/ boost until it opens. Taking offers. It's in great condition. I can email or text pics.

 

Basically what you have is a forge splitter?
