[QUOTE="Steve Bryant, post: 610061, member: 63716"] Gavin, Wrapping the valve doesn't open any part of the system to outside air. It simply "muffles or mutes" the sound made by the vacuum air as it is pulled through the valve. It makes the same sound as it always did, you just cant hear it doing it. Perhaps I could have used a better word than "breathe" to describe what the valve is actually doing. The little cap on top of the valve is actually the electromagnet winding cover. I have tinkered a bit more with this and I think most of the sound is transmitted to the fender through the metal mounting bracket itself. I unsnapped the valve, rewrapped it and tucked it back into it's place without using the bracket. I cant hear it at all when configured in this fashion. Steve Bryant [/QUOTE]
