The exhaust manifolds are cast from an iron alloy with a high nickel content and sealed by means of a steel gasket. Spacers on the securing bolts allow the exhaust manifolds to expand and retract with changes of temperature while maintaining the clamping loads.
The bank 1 exhaust manifold has a connection for the High Pressure (HP) Exhaust Gas Recirculation (EGR) valve.
The engine is equipped with 2 turbochargers, which fix to the exhaust manifolds by a 3-hole flange with a steel gasket.
