If I'm hearing the vids correctly it sounds like an almost metallic, and very rapid, high rpm whine that spools down slowly.

Since you have inlets, I wonder if they are unmasking the sounds of the turbos themselves. With such a fast whine I'm thinking that's what I'm hearing.

Curious if it would still be as audible without the inlets.
