Recently started hearing this noise when accelerating at around 60-80MPH. It only occurs when cruising at roughly 2K RPM, with just slightly more throttle input than necessary to maintain speed. Car drives fine otherwise. No codes.

Video Example 1 - sound happens only briefly at :6s
Video Example 2 - sound occurs just as I start a lane change

I thought I might be interior rattle at first but it just sounds too loud and like something much heavier is vibrating than a piece of interior trim. Any ideas on what this could be? Kiinda makes me nervous that it seems tied to throttle input.

I am lowered on Bilstien b14 kit and on 18inch rims but stock otherwise.
