Eisenmann Sound-Rohr

Eventhough a E46 has a sport rearsilencer, it dosn´t sound very much, therefor Eisenmann developed this pipe, that is mounted instead of the midle silencer (between cat and rearsilencer), it gives a real good sound.
The sound-rohr is not TÜV approved!
Nú spyr ég örugglega eins og algjör kjáni: Hvað er sound-rohr? Hljóð-rör? Og hvar kemur þetta?
Takk.
