Exhaust Manifold

One   end of the exhaust manifold is connected to each cylinder and the other end   is assembled into a tube. The exhaust manifold allows the exhaust gas from   the cylinder to enter into the exhaust pipe. Exhaust manifolds are essential   to cars. For the engine of four cylinders, it has four exhaust manifolds, and   for the engine of eight cylinders, it has eight exhaust manifolds. The   exhaust manifold is also known as the exhaust head section. The exhaust pipe   of an engine is divided into three sections, namely the head section, the   middle section and the tail section. The middle part is a longer tube on the chassis.   The tail section is near the rear bumper and usually equipped with a large   muffler. The exhaust pipe allows the exhaust gas produced by the engine work   to be discharged into the atmosphere and reduces the noise generated during   the exhaust process.
