The Eisenmann E63 / E64 M6 Performance Exhaust enhances the sound and character of BMW’s legendary S85 V10 engine with a deeper, more aggressive exhaust note while maintaining the premium fit and finish Eisenmann is known for. Designed specifically for the BMW E63 and E64 M6, this rear muffler system is available in Sport or Race sound levels to suit different driving preferences. The Race sound level is the preferred option for enthusiasts seeking the most aggressive V10 tone possible, delivering a sharper and more pronounced exhaust character throughout the rev range. The Sport sound level offers a more refined sound profile, making it ideal for owners who prefer a balanced tone or have additional exhaust modifications that may increase overall volume. The naturally aspirated S85 V10 remains one of BMW M’s most iconic engines, and the Eisenmann exhaust has long been regarded as one of the best ways to fully experience its sound. Eisenmann has been handcrafting exhaust systems in Germany for over 30 years and serves as an OE supplier to some of the world’s leading automotive manufacturers. That experience is reflected in the quality, sound, and finish of every Eisenmann performance exhaust system.
