Can the car gear lever be modified?

[AthenaMarie]

Modifying the car gear lever is illegal as it causes inconsistency between the vehicle registration certificate and the actual condition of the car. Below are the hazards associated with car modifications: 1. Carbon fiber engine hood modification: This is the most dangerous modification. The original hood is designed to deform and bend in stages during a collision, whereas modified parts may directly pierce the windshield, leading to accidents. 2. Installing a mushroom-head exhaust pipe: The mushroom-head exhaust pipe reduces intake inertia, resulting in decreased low-speed torque, increased fuel consumption, and reduced power at low speeds. 3. Upgrading to a larger exhaust system: This reduces exhaust backpressure, leading to decreased low-speed torque, and the engine exhaust valves are more prone to burning out due to excessively high temperatures.
