Eisenmann’s masterpiece – the F8x M3/M4 Performance Exhaust System. Eisenmann’s Stuttgart-based engineers have leveraged 30 years of heritage as Germany’s premier exhaust manufacturer as well as decades of experience as OE designers and manufacturers for Porsche and AMG to create the M3/M4 exhaust system.

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 reduced weight. The canisters are machine-pressed into a shape specifically designed for the F8x 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 F8x 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 complete system, with optional resonated or non-resonated mid-pipes, includes everything from the exhaust tips to the 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 F8x’s S55 powerplant to make even more power.

The new “Signature” tip combines what was great about BMW M’s design with the classic Eisenmann LeMans style to create something that is both at home on BMW’s new M car and also an homage to Eisenmann’s own classic tip designs. Eisenmann’s new “Signature” tips are specifically designed to emulate the style of the BMW M tips, to allow our clients to remain within the M realm of design and appearance, while simultaneously having something very unique – the added “LeMans style” inner tip is an Eisenmann hallmark, and has been unique to Eisenmann for over a decade.

If this still isn’t enough for you then you can add the optional Eisenmann downpipes to create the ultimate power and sound experience your M3/M4 deserves!
