In the modification of the intake and exhaust system, the modification of the exhaust system is more popular, because the exhaust system, especially its tail section, not only is clearly visible outside the car, but also can emit awe-inspiring audio and sound, which is one of the few. Modified components that directly provide car owners with visual and auditory stimulation. The original exhaust system has to take into account the constraints of cost, noise pollution and different emission standards in different regions, so it is very conservative in design and will limit the performance of the engine to a certain extent due to the low exhaust efficiency. Therefore, the modification of the exhaust system can often bring unexpected gains to car owners.
The modification of the exhaust system can follow the method from shallow to deep.
1) The general exhaust system modification only involves the tail section of the exhaust pipe. The diameter of the tail section of the exhaust pipe can be appropriately increased and the structure of the muffler can be changed to increase the air flow per unit area, thereby making the exhaust gas emission more Smooth. The most basic modification is to put a more beautiful stainless steel sheath on the end of the exhaust pipe. The advantage is that it is cheap, easy to install, and will not have any impact on the original car.
2) For deeper modification, you can saw off the tail section of the original car's exhaust pipe, weld a special tail throat to the cut part, or directly replace the original special model tail throat launched by a different brand. This tail throat is made of stainless steel. Its biggest feature is that it can emit a low-frequency sound. Although the sound quality is low, it is very refreshing. However, if this modification method is adopted, the car owner must abandon the tail section of the original car exhaust pipe.
3) Deeper modification focuses on the front middle section of the exhaust pipe and the exhaust manifold. The modification of the front middle section of the exhaust pipe involves the modification of the three-way catalytic converter and the inner wall and diameter of the exhaust pipe; the modification of the exhaust manifold involves the arrangement of the exhaust line.
