TWCs are provided in the exhaust manifold sub-assembly and also in the front exhaust pipe assembly.
An exhaust manifold with an integrated TWC is used for warm-up of the TWC in the front exhaust pipe assembly.
An ultra thin-wall, high-cell density, ceramic type TWC is used for the exhaust manifold sub-assembly and a thin-wall, ceramic type TWC is used for the front exhaust pipe assembly.
The ultra thin-wall TWC enables improved exhaust emissions by optimizing the cell density and the wall thickness.
