Bypass valve VS Blow off valve

I currently have the large red Procharger race bypass valve and the thing is freakin LOUD driving down the road, it sounds like a jet which is cool, but cruising at 80 on the interstate it almost drowns out the radio. I'm thinking about selling it and getting a blow off valve so it will only make noise when the throttle snaps shut, instead of venting all the time it see's vacuum. Is there any reason's I shouldn't swap it for a blow off valve?

I always thought the difference between the blow off valve and bypass valve was bypass was routed back into the system and blow off was in the atmosphere.

I have a dsm bov and I don't hear it until you get into boost then let off.

blowoff valve is spring loaded and only vents after you've seen boost and you let off the throttle, bypass valve vents anytime the valve is seeing vaccum.
