The Akrapovič Evolution Line cat-back exhaust in stainless steel with carbon tips and link pipe is specified for 2016–2017 BMW 340i (F30/F31). As a cat-back system it replaces the factory rear section and includes link pipe hardware and carbon-fiber finished tips to refine exhaust flow and appearance for those model years, providing a factory-replacement style upgrade from the catalytic converter back.
