Exhaust System Description
The exhaust system consists of an exhaust manifold, three-way catalytic converter (TWC) in catalyst case, exhaust
pipes, a muffler and seals, gasket and etc.
The three-way catalytic converter is an emission control device added to the exhaust system to lower the levels of
Hydrocarbon (HC), Carbon Monoxide (CO), and Oxides of Nitrogen (NOx) pollutants in the exhaust gas.
