The modification of the car network can be directly replaced, and it can only be modified after being filed by the vehicle management office. According to the latest "Working Rules for Motor Vehicle Inspection", the modification of the vehicle network has been included in the legal scope, so it should be noted that the length and width of the vehicle network should not be changed. The following are the relevant regulations for automobile modification: 1. You can modify the body color (including interior), engine, fuel type and frame number. Only when the body, frame and engine are damaged beyond repair or have quality problems can they be changed. When applying for change, the repair shop certificate and the certificate of origin of replacing the engine, body or frame should be issued at the same time;
2. It is feasible to replace the front bumper after approval, but modifications such as raising the chassis to improve the off-road performance of the car are not allowed. Once illegal modification is found in the annual review, it must be restored to its original state;
3. It is not allowed to widen the tire and modify the air intake system and exhaust system. According to the relevant provisions of the "Motor Vehicle Registration Measures" issued by the Ministry of Public Security, the tire size, modified air intake system and exhaust system of vehicles in use are not allowed to be changed by the state.
