The Eisenmann F8X M3/M4 Center Pipe Set is a stainless steel replacement for the factory resonator sections of the BMW F80 M3 and F82/F83 M4 exhaust system. Designed specifically for the S55 3.0-liter twin-turbocharged inline-six, the Eisenmann center pipes replace the factory resonators between the catalytic converters and the rear mufflers, improving mid-system exhaust flow and allowing more of the S55's inherent acoustic character to reach the rear of the car. The result is a more engaging and involving exhaust note in combination with the factory or an aftermarket cat-back exhaust.

Constructed from 304 stainless steel and handcrafted in Germany, the set is available in non-resonated and resonated configurations. The non-resonated version removes the factory resonators entirely for maximum flow improvement and sound enhancement, delivering a notably more aggressive and direct exhaust note from the S55. The resonated option provides a more moderate enhancement that retains some acoustic management for a refined result while still offering a clear improvement over the factory setup. Both configurations use direct factory mounting points for a clean installation with no modifications required.
