Exhaust Manifold: Description and Operation
INTAKE/EXHAUST MANIFOLDThe aluminum alloy manifold is a cross type with long runners to improve air flow. The runners, attaching below at the cylinder head, also attach above and support an air plenum. The air plenum chamber absorbs air pulsations created during the suction phase of each cylinder. Both exhaust manifolds are a log style made of ductile cast iron. Exhaust gasses, collected from the front cylinder bank, leave the front manifold through an end outlet and are fed through an upper crossover tube to the rear manifold. The collected exhaust from both manifolds are combined at the exhaust outlet, to the exhaust pipe.
