The Eisenmann F8X M3/M4 Performance Exhaust System - Valved is a complete valve-equipped performance exhaust developed specifically for the BMW F80 M3 and F82/F83 M4. Engineered around the S55 twin-turbocharged inline-six, this system uses Eisenmann's electronically controlled valve technology to deliver variable exhaust character, transitioning from a refined sport tone during normal driving to an aggressive, full-throttle exhaust note under acceleration. Multiple internal flow paths work in unison with BMW's Comfort, Sport, and Sport Plus ECU modes to vary exhaust character.
Constructed from high-grade 304 stainless steel and handcrafted in Germany, every component reflects Eisenmann's approach to precision exhaust development. Machine-pressed canisters use deep-draw dies for high rigidity and Eisenmann's signature tone. The system is available with Eisenmann's four-tip configuration in brushed black or carbon fiber finishes, in both Signature straight-cut and LeMans slant-cut styles. An optional Black Series high-temperature ceramic coating improves heat dissipation and corrosion resistance.
