Exhaust Manifold: Description and Operation
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 perforated core graphite 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.
