Steel for the components of the exhaust pipe

Because the exhaust pipe’s temperature is too high, cast iron is generally used as the raw material, and it is mounted on the cylinder head of the engine (behind the exhaust valve). Then there is a metal hose for shock absorption (also sealed inside) and a larger straight pipe behind it. ( The thick straight pipe is the transition pipe and the connecting pipe between the exhaust manifold and the first muffler. From here, the exhaust pipe is a regular steel pipe or iron pipe but it's a little bit bulky). Next is the muffler, which has a structure with a closed exterior and an empty interior. One is for intake and one is for exhaust inside. The intake pipe is in the muffler which has many holes ,(tubes that look like sieves) and slows down the flow of air from the engine into the muffler, then form an air storage chamber inside the muffler. The gas is then vented into the second silencer through another exhaust pipe, the same as the intake pipe of the silencer.
