Do you have helmholtz chambers? From what I have read, every exhaust made for the M3 minus BMW exhaust and maybe Supersprint, drone to an extent. As for me, after putting over 700 miles on my magnaflow set up with the helmholtz chambers, the drone is not there. Getting my test pipes put on and a tune with it soon so I hope to have it sound even better.
