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