EXHAUST SYSTEM
GENERAL
The exhaust system consists of two exhaust manifolds, exhaust pipes and shields, a muffler, spark arrestor, and tailpipes.
The exhaust system directs engine exhaust gases and smoke out and away from the vehicle.
EXHAUST MANIFOLDS
Two exhaust manifolds are mounted to the cylinder heads. The manifolds collect exhaust gases from the cylinders, and
direct them into the exhaust pipes. Two heat shields are mounted on the engine below the right side manifold to deflect
heat from the starting motor.
EXHAUST PIPES
Two exhaust pipes and a crossover pipe collect exhaust gases from the manifolds, and direct them into the muffler.
MUFFLER
The muffler is a conventional-type muffler with baffles to quiet engine noise and create needed exhaust back pressure for
proper engine operation. A heat shield is mounted between the muffler and fuel tank to deflect heat from the fuel tank.
SPARK ARRESTOR
The spark arrestor is mounted to the muffler outlet and is a supplement to the muffler. It contains any sparks from exhaust
heat and allows more time for the exhaust gases to cool before being released.
TAILPIPES
The tailpipes direct the exhaust gases from the spark arrestor out and away from the vehicle to avoid poisonous fumes
from entering the vehicle.
