hi dear community, what do you think of such a folding control ? my v8 exhaust is in factory condition ! at the cold start it sounds ok only if I leave too quiet .. in the inner city I hear hardly which solution is to be recommended in my driving mode ? also no special amg sound .. too loud and too embarrassing .. so if you want to imagine the pictorial .. an old cl 500 from 2006 without cats with plastic bumpers ! does the control have an effect at all ? or is there any in difference? disadvantages for motor ? lg ezzo
