Cast iron has traditionally been used for manufacturing these manifolds due to its durability under high temperatures; however, modern vehicles are increasingly employing lighter materials like aluminum alloys for intake manifolds and stainless steel for exhaust systems to reduce weight and improve heat dissipation.
The configuration of these manifolds varies between different types of engines.

For instance, a V6 engine would typically require two separate banks for its intake and two corresponding banks for its exhaust system. These need careful integration into a cohesive whole that fits within an engine bay without interfering with other components while achieving desired performance characteristics.
Performance tuning often involves modifications to these manifolds since altering their geometry can impact airflow characteristics dramatically. Aftermarket options include larger plenums—spaces where air accumulates before being distributed—to increase volume capacity or headers (a type of exhaust manifold) with equal length tubes for consistent gas expulsion from each cylinder.
Environmental considerations also dictate aspects of manifold design today as emissions regulations become stricter worldwide. Technologies such as Exhaust Gas Recirculation (EGR) systems integrate into these layouts seamlessly whilst maintaining compliance with legislation aimed at reducing pollutants released into the atmosphere.
In conclusion, understanding the intricacies behind intake and exhaust manifold layouts provides insight into how they contribute towards optimizing an engine's functionality while balancing power production against environmental mandates—a crucial element in automotive engineering endeavors tailored toward achieving superior vehicular performance amidst evolving global standards.
