For the first 200 miles, it will drone quite a bit...after 1000 miles most of the drone is gone, and driving at highway speeds puts you way above 2k RPM (where some of that drone occurs)
I've had it on my car, and driving to the meets at highway speeds I can safely say that it does NOT drone at highway speeds

If you have your windows up and the radio turned down low, you will not hear the exhaust....Best exhaust out there hands down!!!

I have found that on my 530 I can hear the exhaust pretty well at 70. Not a bad thing though. At 80 it is just a slight humm in a bass note. At 85 I got pulled over by the cops so I can't comment on that too much.
I will admit that at first I thought I had made a huge mistake getting this exhaust. I've put about 750 miles since installing it and I will say now that I can extremely satisfied with the sound. Hard not to punch it when in a tunnel and when I am pulling into the parking deck at work I have to roll down the window to listen.
