Eisenmann BMW F30 340i / F32 440i Rear muffler

Sport rear muffler by Eisenmann designed for BMW F30 340i / F32 440i (compatible with xDrive).
Made entirely of stainless steel. The system is fitted with silver exhaust tips in a choice of configurations: 2 x 90mm or 4 x 76mm.
Installing this exhaust requires a cutout in the rear bumper and cutting the factory system.
The system can be upgraded with a non-resonated or resonated center section. The center section is not compatible with xDrive.
Eisenmann is a German brand specialising in sports exhaust systems and rear silencers. Its range also includes the Classic Line, developed for owners of classic cars.
Eisenmann exhausts offer a way to give a vehicle a sportier character, with applications tailored to specific cars. When choosing a rear silencer, check compatibility with the exact model, engine variant and existing exhaust components.
Eisenmann begins exhaust development by digitising the available installation space and designing the system in CAD. Production tooling is made in-house, with components formed and laser-cut at its Hemmingen facility. Acoustic development targets unwanted frequencies, focusing on the character of the sound rather than volume alone.
History and development. Jutta and Rolf Eisenmann built the business from 1988. Its exhaust specialism developed alongside metalworking and projects for vehicle manufacturers. The company adopted the name S&R Eisenmann GmbH in 2022; the founders transferred their shares and management to Marcel Brinkwirth around the turn of 2022–2023.
The business today. The brand continues to offer sports exhausts and its Classic Line, manufactured in Hemmingen. Handcrafted products remain part of a business that also undertakes development and small-batch production. The corporate name change did not mean the withdrawal of Eisenmann exhaust products.
