Why Does the Exhaust Make a Popping Sound?

Mainly caused by poor valve sealing. Functions of the car exhaust pipe: Vibration damping, noise reduction, facilitating installation, and extending the lifespan of the exhaust muffler system. Its primary material is stainless steel. The car exhaust bellows, also known as the car exhaust flexible pipe, is installed in the exhaust pipe between the engine exhaust manifold and the muffler, providing a flexible connection for the entire exhaust system. The exhaust pipe connects external elements to the interior of the car, primarily expelling waste gases from the car's interior. Precautions for the car exhaust pipe: The car exhaust pipe is installed between the engine exhaust pipe and the muffler, linking the entire exhaust system together. Its main functions are to reduce vibration and noise, and to some extent, extend the lifespan of the exhaust muffler. Therefore, do not neglect maintenance just because the exhaust pipe is exposed externally. Maintaining the exhaust pipe is essentially a form of maintenance for the car's internal system.
The exhaust popping sound can be quite alarming. Last time I encountered it, I initially thought it was a racing effect, but it actually indicates an exhaust leak. Common causes include corrosion holes in the exhaust pipe, internal damage to the muffler, or incomplete engine combustion leading to unburned gases igniting in the exhaust system. Ignoring this issue can have serious consequences, such as sudden worsening during high-speed driving, potentially causing carbon monoxide to leak into the cabin and harm occupants or damage the engine. I recommend immediately pulling over to inspect the exterior of the exhaust pipe for rust holes or cracks. Use a soapy water test to check for bubbles and confirm leak points. For safety, contact a professional technician for a thorough inspection. Regular cleaning of the exhaust system can effectively prevent such issues.
