Kreissieg F-1 Sound Valvetronic Exhaust for M3(E9X)

This is the valve system for BMW M3(E9X).

With many decades of experience with exotic cars, Kreissieg's engineers have put down significant time and efforts to produce these exhaust systems.

Kreissieg 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.
