Do sedan exhaust pipes have drainage holes?

[AlanDella]

Sedan exhaust pipes do have drainage holes. The exhaust pipe is part of the engine's exhaust system, which includes the front exhaust pipe and the rear exhaust pipe. The exhaust system is responsible for discharging the waste gases produced by the engine while reducing the pollution and noise of the emitted gases. It consists of the exhaust manifold, catalytic converter, exhaust temperature sensor, car muffler, and tailpipe. The functions of a sedan exhaust pipe include: 1. Vibration damping and noise reduction; 2. Facilitating installation; 3. Extending the lifespan of the exhaust muffler system. Maintenance methods for the exhaust pipe are: 1. Avoid water entering the muffler when driving in the rain or washing the car; 2. Regularly clean the dirt inside the exhaust pipe.
