    Study Notes

    • Automotive exhaust systems remove spent gases from the internal combustion engine.
    • Backpressure is the resistance to exhaust gas flow in the system.
    • The exhaust manifold bolts directly to the cylinder head.
    • The catalytic converter converts harmful exhaust emissions into non-harmful compounds.
    • The muffler is used in the exhaust stream to help quiet the sound of engine combustion.
    • The resonator helps to quiet the sound of combustion before the exhaust gases reach the muffler.
    • The tailpipe is the last pipe in the exhaust system.
    • Aftermarket installers can only keep a catalytic converter after it has been removed from a vehicle for 15 days.
    • Mounting hardware is used to attach the exhaust system to the vehicle using brackets hangers and clamps.
    • Clamps are U-bolts that come in different sizes that correspond to the pipe diameter that secure the slip joint connections.
    • Exhaust system components include pipes, mufflers, catalytic converters, hangers, and heat shields.
    • Hangers support the exhaust system and must be flexible to allow for expansion and movement.
    • Heat shields protect the underbody of the vehicle from excessive heat.
    • Inspection of the exhaust system should check for physical damage, holes, cracks, and missing clamps and hangers.
    • Exhaust system damage can result in excessive noise, harmful exhaust gases entering the passenger compartment, and restrictions.
    • Black streaks or soot on the outside of a component can be signs of leakage.
    • Exhaust leaks can be diagnosed by blocking off the tailpipe, using a technician's stethoscope, or using a smoke machine.
    • Carbon monoxide in engine exhaust can be dangerous and must be addressed immediately.
    • Double wall tubing can cause restrictions even when the outer tube looks good.
    • Electronic exhaust gas leak detectors can be used to locate leaks for repair.
