Does anyone try to control another valve like this ?

So in theory, you if you want it to sound louder than stock, you can add another vacuum valve and you can control it by remote control, the question is there is enough OEM vacuum pressure to open the add on valve (it said it will open at aprox. 1 bar) ?
