I noticed this the most while schlepping to my PPF installer on the outskirts of town. There is literally no way to drive the car in 6th gear and keep to within 10 miles of legal speeds without the cabin being filled with a BOOOMING drone.

I'll be keeping an ear out for this on our holiday trip up to the Carolina mountains. The car only has ~500 miles right now. Maybe I should do some before and after measures between now and the break-in service?

Metak, if you need me to take any decible measurements let me know. I'll have to find an app to do it but I've seen a couple on the App Store.
I have the SPL meter at the below link that I used to calibrate my Home Theater. Let me know if you need help with the measurements.

You know Mike, I missed your post/link. I think if your SLP Meter can measure the "peak" not average frequency(Hz) in the C-weighted(full range mode) at ~2300RPM(I think that where the drone is most prevalent) that would be awesome!
