Does Modifying the Mid-to-Rear Exhaust System Damage the Car?
1 Answers
It will have a certain impact on the car. Replacing the full exhaust system mainly increases the diameter of the exhaust pipe, making the exhaust smoother and allowing the car's horsepower to be more easily utilized during high-speed driving. Replacing the mid-to-rear section primarily involves changing the catalytic converter and controlling exhaust backpressure. Theoretically, the more backpressure is released, the smaller the low-end torque becomes, which may slightly reduce acceleration performance, but high-speed horsepower will be better utilized. Additionally, modifying the exhaust system is illegal. Below are relevant extended materials: 1. Illegal Modifications: Small and micro passenger cars are allowed to install front and rear anti-collision devices; cargo vehicles are permitted to add windshields, water tanks, toolboxes, spare tire racks, etc.; and enhancing interior decorations are the three permissible modifications. Any other modifications that alter the vehicle's brand, model, engine type, or change the registered appearance and technical data of the vehicle are considered illegal modifications. 2. Penalties for Illegal Modifications: If a privately modified vehicle is driven on the road, the traffic management department of the public security organ shall confiscate the vehicle, enforce its scrapping, and impose a fine ranging from 200 to 2,000 yuan on the driver, along with revoking the driver's license.
