Moin Men, I’m asking myself a question. I’m thinking if I don’t buy my R8 another exhaust system. Since I’m no longer standing on “just loud”, I’m thinking a lot about OB and HOW to do the whole thing. A very important question here is the performance of the vehicle. The car has flaps installed in the exhaust. Why is that so? They open and close even during the ride. So audible. At high speed the vehicle becomes increasingly la uter- really great! The flaps are closed at low pressure, should this cause more torque from the lower speed band ? That would be my only question, because almost all the systems that I like and are not too loud do not work. These are just bare rear silencers systems. I thank you already in advance. and many greetings from Hamburg
