The�design�of�the�sports�exhaust�system�only�differs�from�the�standard�production�exhaust�system�by
virtue�of�the�internal�design�of�the�rear�silencer.�That�design�feature�in�the�area�of�the�rear�silencer�and
the�controlled�exhaust�flaps�has�made�it�possible�to�give�the�F97/F98�with�M�Sport�exhaust�system�an
even�more�distinctly�powerful,�richer�and�more�emotive�sound�than�the�standard�production�exhaust
system.

In�contrast�with�the�exhaust�flaps�on�the�standard�exhaust�system,�the�exhaust�flaps�of�the�M�Sport
exhaust�system�can�adopt�intermediate�positions.�Therefore,�it�is�possible�for�the�exhaust�flaps�to
be�continuously�variably�adjusted�to�any�position.�On�vehicles�with�the�M�Sport�exhaust�system,�the
exhaust�flap�is�fully�open�in�Sport�mode.
The�sports�exhaust�system�of�the�F97/F98�features�black�chrome-plated�tailpipe�trims�as�a�visual
identification�feature.
A�further,�more�emotive�adaptation�of�the�interior�sound�in�the�F97/F98�with�M�Sport�exhaust�system�is
made�possible�by�a�different�Active�Sound�Design�(ASD)�tuning.
