The Eisenmann Performance Exhaust for the BMW E90 M3 is a handcrafted stainless steel rear exhaust system developed for the BMW E90 M3 sedan and its naturally aspirated S65 V8. It replaces the factory rear muffler with a freer-flowing design that delivers the Eisenmann trademark tone, deep at low RPM and a true performance car scream at high RPM, while improving flow over the stock system.
Built by hand in Germany from stainless steel by the same company that supplies OEM exhaust systems to Porsche and Mercedes-AMG, the E90 M3 system finishes in 4x83mm LeMans tips and is offered in Sport and Race sound levels. Sport gives a refined, deeper tone suited to daily driving, while Race produces a louder, throaty exotic character. Connecting pipes are included, so the system bolts on at the factory mounting points with no cutting required.
The Race version is dyno-proven at 16 hp and 11 lb-ft of torque. Sport measures 75 dB moving and 92 dB stationary at 6,225 rpm with a 25% flow improvement over stock; Race measures approximately 95 dB moving and 102 dB stationary at 6,225 rpm with a 32% flow improvement. Muffler weight is approximately 21 kg.
