What components are included in a vehicle's exhaust system?

The correct choice includes the exhaust manifold, piping, and catalytic converter, which are essential components of a vehicle's exhaust system.

The exhaust manifold collects exhaust gases from the engine's cylinders and funnels them into the exhaust piping. This system then directs the gases through the catalytic converter, where harmful emissions are reduced before being expelled into the atmosphere. Proper functioning of the exhaust system is crucial for vehicle performance and compliance with emissions regulations, as it not only facilitates the safe discharge of exhaust gases but also reduces pollutants.

The other choices contain components that do not belong in the exhaust system. Tail lights are part of the vehicle's lighting system, mufflers reduce noise but aren't the complete picture of the exhaust system layout, and fuel tank and battery are parts of the fuel and electrical systems, respectively. Therefore, the inclusion of the exhaust manifold, piping, and catalytic converter is what defines the exhaust system specifically.
