I've had the MPE for a year and love it. Recently a loud resonance drone
with a metal rattle sound started at 3000-3100 rpm.
It seems that a weld has broken loose in the baffles of the muffler.
I took it in under warranty (2 years) and BMW service department has offered to replace it
Hopefully the next one holds up better over time...
