Exhaust System Construction
WARNING: This page is about a different car, the 2003 Suzuki Vitara. However, it is still accessible from the selected car via links, so may be relevant.
The exhaust system of the vehicle consists of the exhaust manifold, exhaust No.1 pipe (with Warm Up Three-Way Catalytic Converter, WU-TWC), exhaust No.2 pipe (with Three-Way Catalytic Converter, TWC), muffler, seals, gasket, etc. The three way catalytic converter is an emission control device added to the exhaust system to lower the level of Hydrocarbon (HC), Carbon Monoxide (CO) and Oxides of Nitrogen NOx) pollutants in the exhaust gas.
