Maybe I can download the sound meter app for Android and test. Set it to the drivers side at chest level like a car at the light next to me. Then rev the engine and let the BOV's release and test with and without the hose. The BOV's are much quieter when you rev and release in park, but comparing apples to apples it will let me know the difference. With the windows down in sport mode and popping the throttle it sure seems like it is louder. I can only imagine if you had an open window next to it!
Again, any ideas on something to place on the end of the hose extensions to enhance or increase the sound would be great.
