We just installed the REMUS axle back on the shop's M4 and as expected it sounds amazing. Car has stock downpipes & Active Autowerke midpipe.

This video quickly reviews the REMUS exhaust packaging and finish quality. At the end of the video we have sound clips of different settings.

we show 2 different settings:

1-valves open, burble set to max loudness & duration (the most aggressive setting on Bootmod3)
2-valves closed, no burble (quietest setting)

Users can easily adjust the burble tune to make it quieter and/or shorter using BM3.

Hope you enjoy the video, and let me know if you are interested in a video with balanced burble settings.
