I agree on the farting/popping. Unfortunately, the 981S has them in Sport, fortunately it doesn't do them (much) in either Normal or Sport+. It's one reason I rarely have the PSE (sport exhaust) on.

My 340i's m-perf exhaust is very, very mild. It has the mildest popping; none of the annoying staccato machine gunfire.

I find all this extra annoying because it's fake. Faking old carburetors. My w650 did it a bit, just a bit, but that was appropriate because it was a bike with ancient design (and i still had full stock mufflers on).
