A high compression ratio has been realized by adopting 4-2-1 exhaust pipes and reducing residual gas in the cylinders.
The loop structure of the exhaust pipes for the 4-2-1 system takes up less space.
The exhaust system consists of the following parts:
| Part name | Reference |
| Main silencer | |
| Presilencer | (See PRESILENCER [SKYACTIV-G 2.5].) |
| TWC | |
| WU-TWC |
|
| Exhaust manifold |
