Eisenmann's engineers are responsible for designing the OEM systems seen on Porsche and AMG cars, and use this experience to design the best performance exhaust systems in the world. Eisenmann's performance exhausts are built by hand from start to finish to create an old world craftsmanship simply not available with other exhaust manufacturers.
Construction of nearly all Eisenmann exhaust systems, both externally and internally, is 100% light weight T304/T306 stainless steel throughout. The design of each and every system, from tube configuration and size to muffler and box dimensions, are meticulously calculated and optimised to provide maximum performance at all revs, drawing on Eisenmann's vast Motorsport experience.
NOTE: This exhaust requires modifications to the rear bumper for proper fitment!
