This time I have filmed probably the loudest Audi RS6 C7 in Holland till date. The exhaust is custom made with a valvetronic remote so you can drive with open and closed valves. You can see the demonstration in the video! Enjoy! Thanks to instagrammer @philhaffmans for the last shots of this video!
