The Eisenmann Rear Muffler 4x90mm is a handcrafted stainless steel rear exhaust system developed for the BMW G29 Z4 roadster. It replaces the factory rear muffler with a freer-flowing design tuned specifically for the G29, giving the Z4 a deeper, more refined exhaust note developed for this application rather than a generic template.
Built by hand in Germany by the same company that supplies OEM exhaust systems to Porsche and Mercedes-AMG, the muffler is made from T304 and T316 stainless steel with mandrel-formed bends and hand TIG-welded joints that resist cracking under thermal cycling. It is finished with four 90mm tips in straight-cut Signature or slant-cut LeMans design, with chrome outer tips and brushed aluminum, black anodized or carbon inner tips, and bolts on at the factory mounting points.
