TWCs are provided in the exhaust manifold converter sub-assembly and also in the center exhaust pipe assembly*.
*: Except EURO VId-TEMP models
An exhaust manifold converter sub-assembly with an integrated three-way catalytic converter (TWC) is used. This realizes quick warm-up of the catalytic converter, helping to reduce emissions immediately after engine start.
These TWCs enable lower exhaust emissions through optimized cell density and wall thickness.
