DESCRIPTION

The exhaust manifolds( 1 and 2) 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 ( 1 and 3) for thermal protection and noise reduction. The heat shields(1 and 3) are fastened with a torque prevailing nut that is backed off slightly to allow for the thermal expansion of the exhaust manifold.
