The Eisenmann Performance Exhaust + 4x90mm Carbon Tip Set is a handcrafted stainless steel rear exhaust system developed for the BMW F80 M3, BMW F82 M4 and BMW F83 M4 convertible and their S55 twin-turbo inline-six. It replaces the factory rear muffler with a freer-flowing, lighter design that stays quiet while cruising and delivers a deep, aggressive note under full load.
Built by hand in Germany from 304 stainless steel by the same company that supplies OEM exhaust systems to Porsche and Mercedes-AMG, the system uses deep-drawn canisters shaped for the F80, F82 and F83 so they are hidden from the rear view. Multiple internal flow paths work with the factory valve control and the Comfort, Sport and Sport Plus drive modes. It is supplied with a 4x90mm carbon fiber Signature tip set, optionally with black chrome inner tips, and bolts on at the factory mounting points.
Optional Eisenmann center pipes, available resonated or non-resonated, convert the rear section into a complete bolt-on system from the downpipes back.
