Does a New Car's Exhaust Pipe Need Anti-Rust Spray?

[EllieAnn]

New car exhaust pipes do not require anti-rust spray. Exhaust System: The exhaust system generally consists of an exhaust manifold (header), exhaust pipe, flexible connection (bellows), catalytic converter, and muffler. The exhaust system is almost horizontally arranged along the chassis, but the exhaust manifold is connected to the engine and is positioned higher vertically compared to other components of the exhaust system. When water just submerges the exhaust pipe, it cannot enter the engine cylinders. After the water recedes, the water level in the exhaust pipe will definitely drop again, meaning the farther from the exhaust outlet, the lower the water level. At this point, starting the car will not cause water in the exhaust pipe to be sucked back into the engine. After the water recedes, pay attention to the following starting method: Start the car by turning the ignition, but do not press the accelerator and let it idle. During this time, a lot of water will be expelled from the exhaust pipe until it stops dripping. This process won't take long, about 8 minutes.
