Me too, but all you have to do is adjust the nut on the top of the BOV to the sound you want..

Those are bypass valves... hence the flange on the outlet of them.

Also, adjustment screws on bov's are not there to adjust sound... lol, however the change of the sound is just an effect ofo increase or decreasing spring pressure.

That's what I was thinking...lol

Just "adjusting" the sound is messing with the pressure...and I wouldn't want to "adjust" it wrong...
