What is the difference between 200-cell and 300-cell headers?

[DerekAnn]

The differences between 200-cell and 300-cell exhaust headers mainly lie in three aspects. Below is a detailed introduction to these three differences: 1. Emission volume: (1) 300-cell: Vehicles with 300-cell headers have a larger exhaust flow, resulting in correspondingly higher emissions. (2) 200-cell: Compared to 300-cell, vehicles with 200-cell headers have a smaller exhaust flow, leading to lower emissions than 300-cell. 2. Sound level: (1) 300-cell: The sound level of a 300-cell exhaust can reach up to 150 decibels. (2) 200-cell: The sound level of a 200-cell exhaust is around 100 decibels. 3. Exhaust gas combustion efficiency: (1) 300-cell: Due to the larger exhaust flow, 300-cell headers may expel some incompletely burned gases. (2) 200-cell: Compared to 300-cell, 200-cell headers have a smaller exhaust flow, allowing gases to be fully burned before passing through the exhaust. Therefore, the exhaust gas combustion efficiency differs between the two.
