11.2 External exhaust gas system

Each engine should have its own exhaust pipe into open air. Backpressure, thermal expansion
and supporting are some of the decisive design factors.
Flexible bellows must be installed directly on the turbocharger outlet, to compensate for
thermal expansion and prevent damages to the turbocharger due to vibrations.
