Can a car's exhaust be modified?
2 Answers
Modifying a car's exhaust system is illegal. Traffic police can easily detect exhaust modifications based on changes in sound. Here are the specific details: 1. Penalties for exhaust system modifications: Traffic police will issue a ticket and require the vehicle to be restored to its original condition within 15 days. Altering the exhaust pipe constitutes changing the vehicle's structure, which is illegal. Additionally, installing decorative exhaust tips is also considered illegal modification and will not pass annual inspections. 2. Differences in modified exhaust sounds: Normally, car exhaust sounds are relatively soft and not very loud. After modification, the sound volume will be noticeably different from regular vehicles, making the exhaust sound excessively deep or loud, creating significant noise.
Of course, you can modify the exhaust system. I've done it a few times and found it quite fun. The main purpose of modifying the exhaust is to enhance the car's performance and sound effects, like giving the car a new voice, making it more enjoyable to drive. For example, changing the exhaust tip or the entire mid-to-rear exhaust system can improve engine exhaust flow, slightly increasing horsepower, especially during acceleration. In terms of sound, you can tune it to a deep roar or a high-pitched scream, depending on personal preference. However, be careful not to make it too loud, as it might disturb the neighborhood or attract police attention, which wouldn't be worth it. Choosing suitable materials like stainless steel ensures durability. Before modifying, it's best to research local regulations, as some areas require exhaust emissions to meet standards; otherwise, annual inspections could be troublesome. After modification, fuel consumption might increase slightly, but overall, it adds a lot to the driving experience. It's recommended to have a professional shop handle the job to ensure safety. Modifying the exhaust is considered an entry-level modification, with moderate costs, typically costing a few thousand yuan.
