SECTION IV. Engine Exhaust Systems
3-6. General.
The engine exhaust system consists of the exhaust manifold, header pipes, muffler and
other exhaust ducts. Since these engines are turbocharged, the exhaust gases are also
routed through the turbocharger.
Non-turbocharged engines will operate with exhaust
leaks but in a turbocharger system it must be sealed for the gases to properly drive the
turbocharger vanes.
Exhaust manifolds route the exhaust to the turbochargers.
Without the exhaust, the turbochargers will not function properly causing excessive loss
of engine power.
