Nur Mittelschalldämpferersatzrohr??

[GV from Belgium2]

Hello guys, girls,

I want to make my Z4 2.5 a bit louder and deeper (satter)... Does anybody has got the original ESD but replaced the MSD with a "Mittelschalldämpferersatzrohr"??

Thanks and greeeetz from Belgium

PS: I must get a MSD-ersatzrohr installed IN the MSD... For Belgian law, there must be a MSD (checked annualy) but I will put 2 tubes in there
