Why does the exhaust make a sputtering sound and become inconsistent?

[DelLogan]

Exhaust sputtering and inconsistent exhaust flow are usually caused by issues with the exhaust pipe or spark plugs. Below is an introduction to the exhaust pipe: 1. Introduction: The exhaust pipe is part of the engine's exhaust system. The exhaust system mainly includes the exhaust manifold, exhaust pipe, and muffler. Typically, the three-way catalytic converter, which controls engine pollutant emissions, is also installed in the exhaust system. The exhaust pipe generally consists of the front exhaust pipe and the rear exhaust pipe. 2. Angle: The exhaust angle of vehicle exhaust pipes has always been a challenging issue for professional manufacturers. According to surveys, the angle direction of exhaust pipes for sedans and light household vehicles is usually parallel to the ground and facing backward. 3. Drainage: Water dripping from the car's exhaust pipe is a good sign. It indicates that the engine is burning fuel efficiently, and as a result, the exhaust pipe may drip water. This is actually a normal phenomenon.
