Audi R8 4.2 Cat-back F1 Sound Valvetronic Exhaust System

This is the valve system for Audi R8 4.2. With many decades of experience with exotic cars, Kreissieg's engineers have put down significant time and efforts to produce these exhaust systems. Our exhaust systems have very complicated construction to accomplish best exhaust sound quality. Not only the valve controls the loudness, but our system also has unique muffler construction to produce our own exhaust tone. This is how Kreissieg can achieve its high-pitch exhaust sound that no one else can imitate.
