Installation summary

Advanced DIY skills are required to install this Eisenmann rear exhaust system on the BMW G83 M4 Convertible, making it a job best suited for experienced home mechanics or professionals with a lift. The installation process requires precise cutting of the stock exhaust system, careful handling of the factory O2 sensors, and the use of heavy-duty exhaust clamps to secure the slip-on muffler and resonator delete pipes. During the procedure, you must ensure proper clearance around all factory heat shields and allow the exhaust tips to cool completely before performing the final torque sequence to prevent misalignment of the quad carbon-fiber tips.
