What are the symptoms of a broken exhaust flexible joint?

[VonHarley]

If the muffler section of the exhaust pipe is damaged, the biggest impact is that the noise will increase, but it does not significantly affect other performance aspects of the car. However, if the rear section of the exhaust pipe is damaged, it becomes more problematic. Not only will the noise be louder, but the exhaust emissions may also fail to meet standards, necessitating a replacement. Below is relevant information about car exhaust pipes: 1. Introduction: The car exhaust bellows, also known as the car exhaust flexible joint, is installed between the engine exhaust manifold and the muffler. It provides a flexible connection for the entire exhaust system, thereby reducing vibration and noise, facilitating installation, and extending the lifespan of the exhaust muffler system. 2. Usage: It is mainly used in light vehicles, micro vehicles, and buses. Its structure consists of a double-layer bellows covered with a steel wire mesh sleeve, with clamping rings on both straight sections. To enhance the muffling effect, the bellows can be equipped with expansion joints or mesh sleeves internally.
