The Remus axle-back exhaust for the 2018 BMW M5 F90 sedan (S63B44B with GPF) is a vehicle-specific rear section fitted with carbon tailpipes. It replaces the factory axle-back outlet on the F90 M5 and provides carbon-finish tips matched to the M5’s GPF-equipped exhaust routing for a tailored rear appearance.
