The automotive exhaust aftertreatment housing is the outer shell of the exhaust emission control system. It encapsulates catalytic substrates, DPF, SCR modules and other internal components.
It guides exhaust gas to flow evenly through the aftertreatment units to reduce harmful exhaust pollutants. Fabricated from heat-resistant stainless steel, it withstands high exhaust temperature, thermal vibration and corrosive exhaust gas while providing structural protection.
