Exhaust manifold gaskets require metal beads where the gas passes through at very high temperatures and low pressure. These metal beads are always reinforced with metal sheets to resist the component movement that arises from large fluctuations in temperature. Modern exhaust manifold gaskets are made of uncoated, beaded multilayer steel (MLS). The number of sheet metal layers depends on the distortion of the exhaust manifold and cylinder head components. Leaks in the exhaust manifold produce bad exhaust values, a loss of power and increased fuel consumption.
