Eisenmann G80 M3 / G82 M4 Performance Exhaust System

Watching BMW create and engineer their new G8x inspired us and Eisenmann Exhaust Systems GmbH to respond in kind. We knew that we could not simply connect a series of pipes to a generic canister and attach exhaust tips at the end. Every aspect of the design had to be analyzed, evaluated, and perfected until the exhaust system as a whole was absolutely flawless. Eisenmann did not approach the design of this exhaust system with the idea of beating their competitors- Eisenmann’s only peer in this race would be BMW M itself, and no stone could be left unturned.

Each system is constructed from high grade 304 stainless steel, with a specific attention to wall thickness throughout to create the best combination of fantastic sound and optimal weight. The canisters are machine-pressed into a shape specifically designed for the G8x M cars using a series of deep draw dies, resulting in extremely high canister rigidity and contributing to Eisenmann’s signature tone. The canister shape was specifically created to completely eliminate the canisters from the rear view of the car, drastically improving the appearance of the G8x cars. Multiple internal flow paths work in unison with BMW’s Comfort, Sport, and Sport Plus ECU programming, and enable Eisenmann’s valve control to have a variable but drastic effect on the exhaust system’s personality, yielding a quiet tone while cruising and a fearsome growl under full load.

Eisenmann’s Heritage system is available as a rear section or complete exhaust system, enabling M3/4 owners to choose their sound level in stages. The complete system will include everything from the exhaust tips to the back of the BMW downpipes, allowing for a bolt-on solution for easy installation and an aggressive sound. Improved flow capacity gives the exhaust system sufficient overhead for future modifications, removing any restriction in the system and enabling the G8x’s S58 powerplant to make even more power.

While the "LeMans style" inner tip has been an Eisenmann hallmark for decades, the all new massive 110mm LeMans Tip present a unique side cut-out featuring the Eisenmann Signature.

We are thrilled to present the new G8x M3/4 exhaust system to M enthusiasts worldwide!
