Default BPV Suggestions on Open Intake?

I know there's a lot of info out there already on By pass valves / diverter valves, but I dont know whats good on an open intake. (Meaning non-airbox high flow intake).

Although i dont have the intake on now, the stock valve gives a loud and, what i consider ugly, blow back sound. Is there a valve that would either reduce the noise or clean it up to sound smoother?

Default a metal valve will make it sound nice and clean

I'm surprised that you can hear the BPV with the airbox on still...

Default with the airbox you cannot hear anything. its when I take it off and use my other intake,

see my registry pics for the open intake.

i but the airbox back on cause the bpv was too annoying.

Default that's probably because you're running the stock bpv

if it's fluttering, it's probably gone bad too. a metal one like an EVOMS or Forge will improve the sound greatly.
