if by trouble you mean cops... then maybe, lucky for us MB guys we don't get bothered as much as guys in their Honda's when it comes to things like thisIt sounds really hollow rather than deep and muffled if you know what I mean. all those pops is just asking for trouble when your on the streets.
It's not an aftermarket exhaust. It's the sports upgrade option. I believe this is a cost option for you guys in the USA. Fitted as standard in Australia and the UKaftermarket exhaust just to confirm. too loud for me but it would sound great at the track.
btw skip to 2:19 to actually hear the exhaust. the guy is just standing there revving for 2 minutes.
