What metals are inside a car exhaust pipe?

[McLuna]

There is stainless steel inside the car exhaust pipe. Below are specific details about the car exhaust pipe: 1. Meaning: The car exhaust corrugated pipe, also known as the car exhaust flexible hose, is installed in the exhaust pipe between the engine exhaust manifold and the muffler, providing a flexible connection for the entire exhaust system. This helps reduce vibration and noise, facilitates installation, and extends the lifespan of the exhaust muffler system. 2. Structure: It is mainly used for light vehicles, compact cars, and buses. Its structure consists of a double-layer corrugated pipe covered with a steel wire mesh sleeve, with clamping rings on both straight end sections. To enhance noise reduction, the corrugated pipe can be equipped with an expansion joint or mesh sleeve inside. The primary material is stainless steel SUS304, while the clamps and connecting pipes can be made of stainless steel or aluminized steel.
