Yes Santa Claus, there is a Drone !... and it is Not that nice exhaust note. It is that "light load" sound from 2200-2700 rpm. Gator [also from Fl] said that his installation of the Berk Tech Midpipe "reduced" the drone-- hope to hear more from him and others that have changed out a part of their exhaust. [maybe the N55 midpipes ?]. I noted the problem to my dealer when I did the 1200 service. He achnowledged the problem, and "retightened" the exhaust system in different ways two times, but it did not improve the drone. If enough dealers note it as a problem, BMW might look for a fix for those who want it.
