The exhaust manifold is a component of the exhaust system used to collect and carry hot exhaust gases away from the engine. Made from stainless steel the exhaust manifold combines the exhaust gases from several cylinders. The exhaust manifold with a exhaust manifold gasket is bolted to the cylinder head. The left exhaust manifold connects to a crossover pipe that is part of the right exhaust manifold and carries the exhaust gases from the front of the vehicle over the transmission to the right exhaust manifold. The gases are combined in the right manifold and directed on to the three-way catalytic converter pipe that is mounted to the flange of the right exhaust manifold. The three-way catalytic converter pipe with a converter pipe gasket is bolted to the right exhaust manifold.
