Is it illegal to modify a car's exhaust?

[MacArianna]

Modifying a car's exhaust system is not allowed and is considered illegal. Below is a detailed introduction about modifying a car's exhaust system: 1. The car's exhaust system cannot be modified. Neither technical modifications nor aesthetic modifications (such as decorative tailpipes) are permitted. Generally, if caught, you will face fines, be ordered to restore the original condition, and have the modified parts confiscated. Severe cases that cause public disturbance (such as loud "pop and bang" noises) may involve administrative detention penalties. 2. The parts of a car that can be legally modified in China include: body color, rims, exterior decorations, car interior, bumpers, and lights.
