Eisenmann Race Exhaust System for G8x BMW M3 / M4

Eisenmann Race Exhaust System for G8x BMW M3 / M4

The Eisenmann Race Exhaust System for the G8x BMW M3 and M4 is a purpose-built performance upgrade designed to unlock the full character of BMW’s latest generation of M power. Developed with a focus on both sound and performance, this system is meticulously handcrafted in Germany from premium 304 stainless steel, ensuring unmatched quality, durability, and precision. By replacing the restrictive factory muffler with a dual high-flow resonator setup, the system significantly improves exhaust gas flow, reduces backpressure, and maximizes power delivery — perfectly complementing the capabilities of BMW’s turbocharged inline-six. Beyond performance, the Eisenmann Race System delivers an unmistakable motorsport-inspired soundtrack. Its aggressive tone is brought to life through a set of massive 110mm LeMans-style tips, each featuring a unique side cut-out design that sets this system apart both visually and acoustically. The result is a bold and commanding exhaust note that transforms the G8x M3 and M4 into an even more visceral and emotionally engaging driving experience. Engineered with an emphasis on weight reduction and optimized performance, this system reflects Eisenmann’s decades-long commitment to producing world-class exhausts that embody both function and artistry. For drivers who demand uncompromising sound, race-bred performance, and precision German craftsmanship, the Eisenmann Race Exhaust System stands as the ultimate expression of what an exhaust upgrade should be.
