Eisenmann F8X M3 / M4 Performance Exhaust System - Valved

Watching BMW create and engineer their new F8x inspired Eisenmann Exhaust Systems GmbH to respond in kind. They knew they 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 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 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 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 F8x’s S55 powerplant to make even more power.

The “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 M car and also an homage to Eisenmann’s own classic tip designs. The “Signature” tips are specifically designed to emulate the style of the BMW M tips, allowing owners to remain within the M realm of design and appearance while having something very unique - the added “LeMans style” inner tip is an Eisenmann hallmark.

Optional Upgrade: Black Series finish features a high-temperature ceramic coating, specifically engineered to enhance heat dissipation and provide superior corrosion resistance.
