The Eisenmann Performance Exhaust for the BMW E90 M3 is engineered to enhance the character of the S65 4.0L V8 with a more aggressive exhaust note, improved flow characteristics, and handcrafted German construction. Available in both Sport and Race sound profiles, this rear exhaust system delivers the unmistakable Eisenmann sound while maintaining OEM-level fitment and straightforward installation.
Designed as a direct bolt-on solution, the Eisenmann E90 M3 Performance Exhaust includes connecting pipes and integrates with the factory exhaust system without the need for permanent modifications. Constructed entirely from premium 304 stainless steel, each system is hand-built in Germany and undergoes extensive quality control to ensure long-term durability and consistent fitment.
The Sport version provides a deeper and more refined exhaust note while remaining suitable for daily driving. For enthusiasts seeking a more aggressive experience, the Race version unlocks the full character of the naturally aspirated S65 V8 with a deeper, more exotic exhaust tone and increased overall volume.
Beyond sound, the Eisenmann system has demonstrated measurable performance improvements. The Race version offers up to a 32% increase in exhaust flow compared to the factory system and has been dyno tested to deliver gains of up to 16 horsepower and 11 lb-ft of torque.
For customers seeking a more distinctive finish, Eisenmann also offers an optional Black Series treatment featuring a high-temperature ceramic coating designed to improve heat dissipation while providing enhanced corrosion resistance.
With more than 30 years of exhaust manufacturing experience, Eisenmann remains one of Germany's most respected exhaust manufacturers and serves as an OE supplier to several leading automotive brands. That expertise is reflected in the sound quality, craftsmanship, and performance of every Eisenmann exhaust system.
