Exhaust pipe leakage problem

If the car exhaust pipe leaks and needs to be repaired, it must be repaired in the car's 4S shop or repair shop, and the car exhaust pipe cannot be repaired without authorization, so as not to affect the driving safety of the car.

If the exhaust pipe is damaged, it will definitely affect the dynamic performance of the car, but it may not necessarily lose power, but may increase power, mainly depending on which part of the exhaust pipe is damaged. Exhaust pipe damage can be divided into three situations: front-end damage, short-term damage and back-end damage, that is, three kinds of non-catalytic partial damage.

The muffler in the exhaust pipe is damaged, the biggest impact is that the noise will increase, which has no effect on other performance of the car. It is troublesome to damage the rear section of the exhaust pipe, which is not only noisy, but also the exhaust emission is not up to standard and must be replaced.

Extended data:

The leakage of automobile exhaust pipe is introduced as follows:

If there is only a small hole in the exhaust pipe, it will not lead to a serious increase in vehicle fuel consumption. Theoretically, if the exhaust pipe is completely removed, the exhaust resistance will disappear completely, which will lead to the increase of engine power and fuel consumption. There is no silencer in the exhaust pipe of racing cars (including motorcycles) to reduce the exhaust resistance, but the noise is huge.

Welding is the most economical method. Some cars have many welding patches on their exhaust pipes, just to save money. Corrosion of exhaust pipe indicates that the engine has good emission. The obvious increase in fuel consumption may be caused by the low temperature in winter, and other special factors may include excessive carbon deposition in the engine.
