Car vent modification

Automobile exhaust hole refers to the exhaust port connected to the combustion chamber, through the exhaust manifold (that is, the head section), the middle section of the automobile exhaust hole (including the catalyst section), to the tail section of the exhaust pipe, which emits combustion exhaust gas. Process. The exhaust system has two main functions. One is to guide the high-temperature exhaust gas after the fuel has been burned to the rear or side of the car, so as not to affect the occupants in the car; the other is to use a muffler to reduce the working noise to the allowable limit to protect surroundings.

The modification of the exhaust system is also divided into primary modification and advanced modification. Generally, the modification of the exhaust pipe only involves the tail section, that is, it only needs to increase the diameter of the tail car exhaust hole, so that the air flow passing through the unit area increases, so as to discharge exhaust gas in time. The primary modification only needs to saw off the tail section of the car exhaust hole and weld the thicker pipe.
