CONSTRUCTION
A stainless steel exhaust manifold converter sub-assembly is used. This achieves a reduction in noise, ensures heat resistance, and realizes quick warm-up of the catalyst immediately after engine start, helping to reduce emissions.
The exhaust manifold converter sub-assembly with an integrated three-way catalyst (TWC) is used. This realizes quick warm-up of the catalytic converter, helping to reduce emissions immediately after engine start.
The EGR system, which extracts emissions from downstream of the catalyst, is used. For the EGR system, refer to Emission Control System.*
