Matters needing attention in automobile modification
After the air intake system is reformed, the exhaust system should be further reformed. It is popular to change the tail section of the exhaust pipe into a straight row mode. You can see a thick exhaust port from the back, and you feel that the power of the vehicle seems to be great. If you change the front and middle sections of the exhaust system, you need professionals to do it.
Because the exhaust is too smooth, it may affect the torque of the engine at low speed; When replacing the front and middle sections of the exhaust pipe, attention should be paid to the technical content and actual test. There is also a two-tone in-line barrel, which can be used for daily use with a small muffler, which is similar to that without modification.
