All M cars should have theater—they are designed to entertain, baffle, and methodically extract not only mechanical performance, but an emotional one as well. Eisenmann’s success is predicated on delivering a heightened experience through manufacturing hand built, German made exhaust systems—they are responsible for some of the finest exhausts for BMW M cars since the company’s inception in 1988. This vast experience has afforded Eisenmann access to both cutting edge technologies and an engineering staff committed to delivering at or above Eisenmann’s stringent standards.
