Eisenmann Performance Exhaust - BMW E31 850Ci (M73)

The Eisenmann E31 850Ci Performance Exhaust is a stainless steel rear exhaust system developed for the BMW E31 850Ci equipped with the M73 V12 engine. Replacing the factory rear muffler, the system improves exhaust flow and delivers a more engaging exhaust note from the E31's twelve-cylinder.

Built from 304 stainless steel and handcrafted in Germany, the system is available in Sport and Race sound tunings. Sport provides a refined enhancement suited to the grand touring character of the 850Ci; Race delivers a more aggressive note for performance-oriented use. Both install on factory mounting points with no modifications required.
