Blow off Valve question?

[PakmanMP5]

Which Blow off Valve makes a flutter sound when relieving pressure?
I drove my friend's MR2 today and he had one it sounded soooooo sexy and I was wondering which BOV makes that sound

Why don't you ask your friend? You say he had it on his car so he would know best.

Lots do that depending on the hardness of the BOV, how much PSI are going through them etc. With my Greddy Type-S, at about 1-3 psi it flutters anything higher it just blows normally.

Well your best bet is to take a picture of the BOV on your friends' car and post it here. Then we'll tell you what it is. To get that identical sound, getting the same BOV might not be enough, because it may produce a different sound on different engines/setups. So just buy his engine.
