The Eisenmann F90 M5 Performance Exhaust System – Valved is a precision-engineered exhaust solution developed to enhance sound, reduce weight, and elevate the overall driving experience of BMW’s F90 M5. Designed and manufactured with Eisenmann’s renowned attention to detail, this system delivers a refined balance between daily drivability and aggressive performance when demanded.
Each Eisenmann F90 M5 Performance Exhaust System is constructed from high-grade 304 stainless steel, with carefully controlled wall thickness to achieve an optimal combination of durability, reduced mass, and acoustic quality. The exhaust canisters are formed using a multi-stage deep-draw pressing process and shaped specifically for the F90 M5 chassis. This results in exceptional structural rigidity while producing Eisenmann’s signature exhaust tone. The compact canister design also ensures the mufflers are hidden from the rear view, significantly improving the visual presentation of the vehicle.
Internally, the Eisenmann F90 M5 Performance Exhaust System – Valved features multiple airflow paths that work seamlessly with BMW’s factory Comfort, Sport, and Sport Plus drive modes. Integrated valve control allows the exhaust character to adapt dynamically, remaining subdued and refined during highway cruising, then opening up under throttle for a deep, aggressive growl that matches the M5’s performance potential.
This Eisenmann F90 M5 Performance Exhaust System is available as either a rear section or a full exhaust configuration, allowing owners to tailor sound and performance in stages. The complete system replaces everything from the exhaust tips forward to the factory downpipes, providing a true bolt-on solution with straightforward installation and a dramatic increase in sound presence.
For those seeking an additional visual and functional upgrade, the optional Black Series finish features a high-temperature matte black ceramic coating engineered to improve corrosion resistance and heat dissipation while delivering a stealth-inspired appearance.
Eisenmann has been handcrafting exhaust systems in Germany for over 30 years and serves as an OE supplier to some of the world’s leading automotive manufacturers. That experience is reflected in the quality, sound, and finish of every Eisenmann performance exhaust system.
