Can Citroen Fukang 8v change crankcase exhaust gas into direct exhaust?

Hello, I have a few questions. First, you may smell exhaust gas when you are circulating outside or opening the window. Second, if it is winter, the straight exhaust pipe you replaced may freeze up, which may lead to the danger of excessive pressure in the valve chamber and possible explosion. We have encountered many cases in our store, hoping to help you with your car use. Ask the car master. 4S shop professional technician, 10 minutes to solve.
