Stumpy, if you are willing to go to Fort Worth there is a shop there that might be able to help you with a Flo-Pro set up:

Kinneys Exhaust




I just took my Flowmaster off a couple of weeks ago for the same reason as you (drone) and went to a Flo Pro and its' way better. I can take a video for you if you like.........

I have a little drone at 15-1700 rpm, but anywhere else and the drone is gone.
