The exhaust manifold in a Jeep is located down to the sides of the engine below the valve covers. A heat
shield covers them and the spark plugs are cradled by them
The exhaust manifold is tasked with collecting the exhaust fumes generated by an internal combustion engine and conveying them towards the catalytic converter or turbocharger.
Exhaust manifolds are often made of alloyed cast iron, which is able to withstand the high exhaust temperatures.
Exhaust manifolds are subject to high thermal stress because they are the first component to convey exhaust fumes away from the engine.
The design of the exhaust manifold has a significant influence on the performance and torque characteristics of an engine, as does the design of the connected pipes.
