The Eisenmann Sport Performance Exhaust for the BMW E82 1M is a handcrafted stainless steel rear exhaust section developed for the BMW E82 1M coupe and its twin-turbocharged N54 inline-six. It replaces the restrictive factory rear muffler with a freer-flowing design that gives the 1M a deeper, fuller exhaust note under load while staying civil at cruising speed, and it frees up flow for the turbocharged engine without adding drone.
Built by hand in Germany from stainless steel by the same company that supplies OEM exhaust systems to Porsche and Mercedes-AMG, the Eisenmann Sport exhaust for the E82 1M finishes in four 83 mm tips, offered in standard stainless or Black Series with matte black coated tips. Optional Eisenmann center pipes (B5422.00000 and B5422.00001) convert the rear section into a full downpipe-back system, and every configuration bolts on at the factory mounting points with no cutting or modification required.
The complete system with center pipes weighs 59.4 lbs. The rear section can be installed on its own first and the center pipes added later for a louder, more open character.
