I am looking at purchasing an ECS kit and was wondering how loud the quiet blow off valve is? With my Z06 being a daily driver, is this thing going to drive me crazy? Do you hear this thing all the time? I wish there was some supercharged cars close to me I could hear. Thanks for any input.

New Tial or old setups with bosch? It only makes noise when you make boost then let off. Daily I don't hear anything unless I'm on it.

All our kits come with the Tail BOV, they make a little noise even with the "Q", but for zero noise we can add another one to the kit.
With the winter special going on now, we can work up a great price for you so it's no additional charge for you.

I have the procharger pro flo valve and I actually took the filter off to make it louder. The air blowing out isn't too loud. You can hear it as your RPMs increase if you are part throttle and bypassing boost or the initial rush of air when you go from WOT and let off.

Normal driving I can't hear it at all. I think the procharger itself is louder than the BOV.
