need HELP with bpv

^ If you still have the stock airbox and you installed an aftermarket bov it will still be really quiet. I did the same thing but with a ebay type s and once i put on an sri it sounds so much better. I still mute the radio when using cruise control while im going uphill to hear the turbo sucking in. Love it
 
I have an ebay type s and it works great. I took it apart and removed the larger spring and under no circumstance do i get flutter. And you can get a recirc for the type off **********s website so it goes right into the recirc line. But im not trying to talk you into just simply stating.
