3D printing and advanced manufacturing techniques are making it easier to create complex manifold shapes and designs that improve flow dynamics. For instance, in July 2024, DMZ Engineering started Multi Jet Fusion (MJF) 3D printing for structural engine components, focused on developing efficient racing exhaust systems. The company has broadened its expertise to include MJF and Selective Laser Melting (SLM) technologies for cutting-edge motorsport applications.
Governments worldwide are also implementing increasingly stringent emissions regulations to reduce the environmental impact of vehicles. Standards such as Euro 6 in Europe, BS VI in India, and CAFE standards in the U.S. push manufacturers to develop advanced exhaust systems that minimize harmful emissions. These regulations require exhaust manifolds to be more efficient at controlling pollutants like nitrogen oxides (NOx), carbon monoxide (CO), and particulate matter (PM). To meet these standards, automakers are adopting high-performance materials and designs that improve heat management and enable more efficient catalytic converter placement.
