The tail section of exhaust gas includes pipes, silencing packages, and car silencing tailpipes (ventilation holes), which are used to reduce noise and for decoration.
Similar to the dual output of certain performance cars; The middle three on the Ferrari 458; Double sided dual output of Nissan GTR; On Pagani, there are four exits in the middle. They are typical representatives of large multi tailed throats.
Generally speaking, the size of a universal tailpipe depends on the vehicle's displacement. The larger the exhaust pipe, the more exhaust gas is discharged, so the larger the displacement, the more and thicker the tailpipe. However, this is not the case!
For example, some smaller displacement cars can also see dual output in the universal tailgate YY, but this is different from large displacement cars. High power cars often have two or one thick pipe leading to two small muffler packs, and then to dual exhaust tailpipes.
Double out high-performance car
Moreover, small cars have a single tube and are relatively thin, which leads to a large silencing package and then splits into two tailpipes, mostly for decorative purposes.
Dual exhaust for small cars.
Of course, there are also some special features, such as the single-sided output of the old Mitsubishi EVO, the single-sided output of the old Subaru STI, the single-sided output of the old GTR, the middle single output of the Megana RS, and the middle single output of the Megana RS, which are relatively small, so they will not affect the flow of exhaust gas, after all, they focus on performance.
The noise reduction package of the exhaust pipe not only has the function of reducing noise, but also can change the exhaust airflow through internal design to change the exhaust sound, which is also the reason for the unique sound wave generated during exhaust.
