THE BEECHMONT CREST AUTOMOTIVE LEARNING ZONE
Exhaust Manifold
The exhaust manifold encloses the exhaust port openings. The exhaust manifold is bolted onto the cylinder head directly over these openings. A gasket fits between the cylinder head and the exhaust manifold.
The exhaust manifold is also connected to the exhaust header pipe. (The header pipe transports exhaust gases to the catalytic converter or muffler.) The connection between the exhaust manifold and the header pipe is sealed with an O-ring or gasket.
Cast iron is standard material for exhaust manifolds. However, high-performance exhaust manifolds may be constructed of stainless steel or lightweight steel tubing.
