The Eisenmann Black Series Performance Exhaust is a handcrafted stainless steel rear exhaust system developed for the BMW E90 M3 sedan and its naturally aspirated S65 4.0L V8. It replaces the factory rear muffler with a freer-flowing design that delivers a deeper, more exotic exhaust note while maintaining OEM-level fitment.
Built by hand in Germany from 304 stainless steel by the same company that supplies OEM exhaust systems to Porsche and Mercedes-AMG, the Eisenmann E90 M3 exhaust is offered in Sport and Race sound levels. Sport provides a refined tone suited to daily driving, while Race unlocks the full character of the S65 with greater volume. Connecting pipes are included, and the system bolts on at the factory mounting points. The optional Black Series upgrade adds a high-temperature ceramic coating in gloss black or matte black for heat dissipation and corrosion resistance.
The Race version offers up to a 32 percent increase in exhaust flow compared to the factory system and has been dyno tested to deliver gains of up to 16 horsepower and 11 lb-ft of torque.
