today i just deleted the front muffler only, all i can say i,m pleased with the sound , no drone at all , i,m over 50 years old, and do not want a screaming car
it took only one hour for putting out the fron muffler, and replace it with a straight pipe ( pictures follow )
in comfort mode when driving easy there is no sound difference, but flooring the gas a bit, you can hear now a nice burble sound. this is how it should sound ....
a happy m240i driver...
