Section IV.
ENGINE EXHAUST SYSTEMS
5-13.
GENERAL
The engine exhaust system consists of the exhaust manifold, muffler, and pipes to
route the gases out of the vehicle.
Turbocharged engines have the exhaust gases
routed through the turbocharger to drive the vanes.
Damage to the muffler or pipes
(not including the ducting for the turbocharger drive circuit) is inconvenient, but
the vehicle can still be operated.
Care must be taken, however, to keep carbon
monoxide out of the crew compartments.
Turbocharger drive circuits must be
repaired or engine performance will be degraded.
