Will Traffic Police Stop Vehicles with Variable Valve Exhaust?
3 Answers
Variable valve exhaust systems may be penalized by traffic police, as no unit or individual is allowed to assemble motor vehicles or arbitrarily alter the registered structure, construction, or characteristics of a motor vehicle. The structure of a vehicle includes four mandatory standards: body color, length, width, and height, as well as the engine and related technical parameters. Below are relevant details: 1. Regulations: According to the provisions of the 'Road Traffic Safety Law of the People's Republic of China,' China prohibits the assembly of motor vehicles and imposes strict management on vehicle modifications. There are principled regulations stating that no unit or individual may assemble motor vehicles or arbitrarily alter the registered structure, construction, or characteristics of a motor vehicle; nor may they change the model, engine number, frame number, or vehicle identification code of a motor vehicle. 2. Variable Exhaust Valve: Modifying a variable exhaust valve essentially involves creating an additional pathway in the exhaust pipe, allowing exhaust gases to bypass components like the muffler, thereby altering the vehicle's noise level. When the valve is closed, exhaust gases can only exit through the original route, so the sound remains unchanged.
As a car owner with some knowledge of regulations, I want to say that modifying a variable valve exhaust system can indeed get you pulled over by traffic police. Why? Because in our country, vehicle modifications must comply with emission and noise standards. If you modify the exhaust system to make it excessively loud or exceed emission limits, traffic police can detect the abnormality by smell or sound during roadside checks and immediately pull you over to issue a fine. According to traffic laws, such illegal modifications may result in a fine of 200-2,000 RMB, a 3-point deduction, and in severe cases, temporary vehicle impoundment. I personally witnessed a friend who modified his valve exhaust and drove in high-sound mode in the city center, only to get caught and fined. I recommend consulting professional institutions before making any modifications to ensure compliance with national standards. Remember, environmental inspections are becoming increasingly strict—don’t invite trouble just to look cool. Safe driving is the top priority. Drive modestly in daily life and opt for certified modification parts to reduce risks.
I'm a car modification enthusiast who has been playing with performance cars for years. The variable exhaust system can produce an explosive sound, which is super cool. But I've been pulled over by traffic police several times because the valve noise was too loud and disturbed the public. Nowadays, traffic police enforce the law quite strictly—they carry decibel meters, and if the noise exceeds the limit, you can be fined. My advice is to avoid using the high-profile mode when driving around the city with such an exhaust system. Based on experience, it's best to avoid using the valve at night or add a silencer component. Also, after modification, go to the vehicle management office to register, which can reduce the chance of fines. Safe driving is the top priority—don't get into trouble just for fun. Sharing these little tips hoping they help you.
