The drone is measurable. I am currently attempting to nail down the exact frequency at ~2300RPM in 6th. I'm trying to get a good recording to capture and analyze. I was planning on doing a thread for those looking for a solution to the drone. There is an equation that you can use to calculate the length of tubing(closed end Helmholtz chamber) to weld inline prior to the exhaust that will not affect airflow(air will not pass through) but will absorb the drone causing frequency. (on my phone currently and don't have the equation handy) The diameter will be the exact same as the existing OEM piping. The exhaust will sound pretty much exactly the same across the entire frequency spectrum except for the specific drone frequency.

Thanks Metak for the constructive note - I look forward to what you may come up with. To others, I'm not trying to recreate a thread on "if there is a drone or not". I enjoy the exhaust note (not sure my neighbors do at 7am when I leave for work
), but as many have said, there is a "drone" at a certain RPM. I know what a nice exhaust note is, as I have had it on several other cars, but I'm not talking about exhaust note. Yes, and I change gears to help. I'm simply talking about that specific RPM range where there is resonance (or drone as many have called it) - not the great exhaust note that the 1M has - that can be annoying to some, and if there is something that can be done to filter out the drone, but not remove the beautiful exhaust note on the car.
