Have you tried removing the sound tube under the hood?
I removed that ugly thing on the day I bought the car!
Thanks for your input. I'd hate to spend $600+ and be disappointed.
I agree with your definition of drone. That's exactly what it is. So if you hear your muffs in the 70 mph arena as I do, you no doubt hear them in city driving at that same rpm. Maybe what I'm hearing is not drone? I've considered that possibility.
