The Eisenmann E85/E86 Z4 Performance Exhaust is a stainless steel rear exhaust system developed for the BMW E85 Z4 Roadster and E86 Z4 Coupe equipped with the M54 engine and M-Sport bumper. The system replaces the factory rear muffler, improving exhaust flow and delivering a more engaging exhaust note from the Z4's inline-six.
Built from 304 stainless steel and handcrafted in Germany, the system is available in Sport and Race sound tunings, with a choice of twin 76mm or quad 76mm round tip exits. Both versions use factory mounting points with no modifications required.
