BMW F12 / F13 640i Coupe FI Exhaust (Frequency Intelligent Exhaust) high-performance valvetronic exhaust system is direct replacement bolt on system manufactured out of a high-grade T304 stainless steel that offers an exhilarating soundtrack.

The unique sound and performance for BMW F12 / F13 640i Coupe is achieved through individually designed muffler internals that are fabricated to offer an ultimate driving experience.
