Context: I own a 440i with the MPPSK exhaust, so I’m speaking from experience here.
When I got my car, it was fun for a bit to get it to do the pops and bangs. But the rare times that my car doesn’t pop on downshift, it sounds so much better. It has such a great natural growl that I now wish my MPPSK exhaust didn’t pop because it just sounds incredible without it.
Now I just find the pops and bangs obnoxious and over the top, especially now that everyone and their mothers with a BMW is popping and banging.
I like the quiet, throaty, inoffensive burbles, but not the pops and bangs. But every stock BMW I’ve driven does the burbles, not pops and bangs
