Show original supplier description
The Eisenmann Sport Exhaust is a German-made, polished stainless steel performance cat-back system designed specifically for BMW E46 323i, 323Ci, 328i, and 328Ci models. Built in-house near Stuttgart, this system uses T304/T306 stainless steel and is engineered to strict tolerances for reliable fitment, utilizing factory hangers and gaskets for straightforward installation. It features 70mm round, straight-cut tips intended to provide a more aggressive aesthetic compared to the stock setup. This system is explicitly not compatible with Convertible models. Each unit is built to order, requiring a production lead time for shipment from the factory in Germany. As with many performance exhausts, it is the vehicle owner's responsibility to ensure compliance with local and federal sound regulations. The Eisenmann Sport series is tuned to provide a distinct, deep growl without being overpowering, ensuring a sporty sound that remains audible inside the cabin without causing excessive noise pollution. For enthusiasts looking to further customize their exhaust tone, this muffler can be paired with optional center pipes, such as a free-flow resonator for civility or a straight pipe for increased volume. The system does not increase emissions or trigger check-engine lights on properly maintained vehicles.
