What are the advantages and disadvantages of modifying the exhaust system?

[DelEvelyn]

Advantages of modifying the exhaust system: 1. Enhances visual aesthetics; 2. Improves auditory effects; 3. Reduces exhaust backpressure, benefiting vehicle performance at high RPMs. Disadvantages of modifying the exhaust system: 1. If the catalytic converter is altered, vehicle emissions may fail inspection; 2. Changing the muffler can alter exhaust backpressure, affecting exhaust noise or causing abnormal sounds; 3. The weight change of the entire exhaust muffler system can alter vibration and noise, potentially leading to fractures during use. Below are the functions of the exhaust pipe: 1. Reduces vibration and noise, extending the lifespan of the exhaust muffler system: Since the exhaust gases leaving the engine are under high pressure, they produce significant noise that can be unacceptable. The exhaust pipe plays a major role in noise reduction. 2. Reduces pollutant emissions: The core components are the catalytic converter and muffler. The catalytic converter transforms harmful gases such as CO, HC, and NOx from the vehicle's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction processes.
