MANIFOLD - EXHAUST
DESCRIPTION
The exhaust manifolds are log style with a patented flow enhancing design to maximize performance. The exhaust
manifolds are made of high silicon molybdenum cast iron. A multi-layer stainless steel exhaust manifold gasket is
used to improve sealing to the cylinder head. The exhaust manifolds are covered by a three layer laminated heat
shield for thermal protection and noise reduction. The heat shields are fastened with a torque prevailing nut that is
backed off slightly to allow for the thermal expansion of the exhaust manifold, with the exception of the nut, which
also secures the oil dipstick tube bracket. That nut should not be backed off.
OPERATION
The exhaust manifolds collect the engine exhaust exiting the combustion chambers, then channels the exhaust
gases to the exhaust pipes attached to the manifolds.
