The Eisenmann 328i / 428i Unresonated Center Pipe is a precision-engineered, T304 stainless steel center pipe designed as a direct-fit replacement for BMW F30, F31, F34 328i and F32, F33, F36 428i models. The unresonated design maximizes exhaust flow and produces a more aggressive exhaust note compared to the resonated variant. Available in automatic and manual transmission configurations.
Eisenmann has supplied OEM exhaust systems to Porsche and AMG for decades. Every Eisenmann center pipe is handcrafted in Germany using mandrel-bent tubing and TIG-welded construction for precise OEM-quality fitment. This center pipe pairs with compatible Eisenmann rear mufflers to create a complete performance exhaust system for the BMW F3x 328i and 428i.
