Is Filing Required for Modifying Exhaust Sound?
2 Answers
Modifying the exhaust sound does not require filing with the vehicle management office. Below is relevant information about vehicle modifications: 1. Relevant Regulations: According to the motor vehicle registration regulations, any changes to the body color, model, performance, purpose, or structure of a licensed motor vehicle, as well as replacement of the frame, body, or engine, must be reported to the vehicle management office for modification registration. 2. Modification Categories: Modifications are divided into fine modifications and general modifications. The commonality is that the synthetic materials used are the same, all being parts of the mecha (hands, feet, head, body, engine, core, control cabin). Weapons, ores, and materials obtained from defeating monsters are not included. The progress added is calculated based on level, with white and green parts at a 1:1 ratio and blue parts at a 1:2 ratio.
Let me talk about modifying the exhaust sound because I’ve learned my lesson the hard way. Last year, on a whim, I installed a new exhaust system for my car—it had a deep, roaring sound, and driving it felt incredibly cool. But just a few days later, the police pulled me over, citing excessive noise, and fined me on the spot. That’s when I realized that in many places, like major urban areas in China, modifying your exhaust to make it louder is illegal, and you might even need to register the modification with the vehicle management office to prove it meets standards. I asked the repair shop owner, and he said it depends on local regulations—generally, exceeding 80 decibels could cause trouble. The registration process is a hassle, requiring noise tests and submitting proof, and there’s a chance it might not pass. Now, I always advise friends not to modify their exhaust recklessly and to check the rules with their local vehicle management office first. Otherwise, they risk getting their car impounded or failing the annual inspection. Plus, improper modifications can even hurt engine efficiency—totally not worth it.
