Recirculating and venting are the same thing. Did you ever see a WRX BOV? The flange is fucked up but its pretty much the same thing as a DSM. It'll recirculate the air into the atmosphere ;)

yes, I realize that too.

Typically the ones made especially for venting have a horn or make a gay noise like the HKS (isn't that the tweet one).

i'll try to post some pics..(they do look alike..)

ya the construction looks identical, the only thing is the flange is a wierd shape. it doesn't matter if its made for recirculating or not, if you leave it open it makes a 'whoosh' noise. not a 'psst psst' squawk like the hks/greddy. its more like a blitz whoosh. in the wrx, with it tucked down and the opening faced down, i can tell you that with the hood opened its very loud, but with the hood closed its barely audible. so positioning will be the difference unless you put a horn on it imo.

Here is my wrx blow off valve.

Like XDEep said, it has a "whoosh" sound. I like it
