I would lift the Z and check, that sounds like an air leak

find anything, though the inlet pipes are pretty hard to check. Turbos I believe are clocked on both sides... I think the ash inlet pipes could have potential to leak with vacuum. They have "play" in them with how they bolt up to the turbo inlets.

I get the same sound. I have 700BB's and the 370 pops, too.

Did you try with the "regular" POP filters?

Seconded. That sounds pneumatic, not mechanical. (n/m)
