I actually tried this exhaust with different downpipes.

With catless downpipe, it droned little bit between 1.8 to 2.2k rpm.

With high flow catted downpipe, it did not drone much. Drone level was similar to my previous car 135i with bmw performance exhaust and hfc downpipe.

I haven't tried it with stock downpipe, but I assume that drone level will be similar to stock exhaust with golf tee mod.
