Yes I did install the crossmember bar between the 2 exhaust pipes before splitting off to each muffler. Only thing I can think is maybe that rear exhaust OEM hanger has something to do with it. I removed that piece off my stock 535i and used the stock m5 hangers which don't have that big metal block piece on it. The drone is much more tolerable now with exhaust valves closed position all times. Too bad 535i don't have the control to exhaust flaps.
