Default I'm guessing they are. When mine were done, the blowoff wasn't loud, but it was there.
When they were healthy, there was absolutely no audible noise at lift.

Default Yeah, I just test drove a friends '00 with a torn boot...that's exactly what it sounded like.
I looked at him like, "no you didn't! You did not put BOVs on this car!" Sure enough his "booty" was ripped! :P

tbb noise would occur more under boost , not under vacuum ("letting off gas"
