• Expander

• Shield

• Manifold

• Muffler

Exhaust _____ pressure is the pressure developed in the exhaust system when the engine is running.

• Trailing

• Back

• Spark

• Neutral

Overtightening exhaust system clamps can cause leakage.

• True

• False

Which of the following is used to reduce the amount of exhaust pollutants entering the atmosphere?

• Heat shields

• Catalytic converter

• Pyrex thermal packing

• Cylinder head exhaust ports

This is the first part of the exhaust system, what is it called?

• Intake manifold

• Downpipe

• Tail pipe

• Exhaust manifold

Each of the following is a major part of an exhaust system EXCEPT:

• Muffler

• Hangers

• Flywheels

• Header pipe

In some dual exhaust systems, the part that connects the right and left header pipes together to equalize back pressure for a slight increase in engine power is called the:

• heat shield

• catalytic converter

• exhaust pipe

• crossover pipe

Technician A says to use a 6-point socket to loosen and remove exhaust system fasteners without stripping nut and bolt heads. Technician B says to use rust penetrant or heat on corroded exhaust system fasteners. Who is right?

• A only

• B only

• Both A and B

• Neither A nor B

This component is fitted within the exhaust system and it reduces the amount of toxic emissions from the engine. What is this component called?

• Filter

• Dogalytic converter

• Gas analyser

• Catalytic converter

Technician A says that the exhaust system can help quiet engine operation by muffling the sound of exhaust gases shooting out of the exhaust ports. Technician B says that the exhaust system can lower emissions by treating the exhaust gases. Who is right?

• A only

• B only

• Both A and B

• Neither A nor B
