The Eisenmann F90 M5 Center Pipe Set is a stainless steel replacement for the factory resonator sections of the BMW F90 M5 exhaust system. Developed for the S63 4.4-liter twin-turbocharged V8, the Eisenmann pipes replace the factory resonators between the catalytic converters and the rear mufflers, reducing flow restriction and enhancing the exhaust note of the S63 across the RPM range.
Constructed from 304 stainless steel and handcrafted in Germany, the set is available in non-resonated and resonated configurations. The non-resonated version eliminates the factory resonators to maximize exhaust flow and volume, delivering a more aggressive and direct exhaust note from the S63 V8 that gives the M5 a more overtly performance-oriented character. The resonated option provides a more moderate enhancement while maintaining the refinement expected from the F90 M5 platform. Both versions use factory mounting points for a direct installation with no modifications required.
