In a combustion engine fitted with a catalytic converter, which pair identifies the component collecting exhaust gases from the cylinders and the one reducing pollutants through chemical reactions?

Correct answer

The exhaust manifold and catalytic converter.

The exhaust manifold and catalytic converter, respectively. An exhaust system does not consist of only those two parts: it may include pipes, silencers, sensors and other treatment devices depending on the vehicle. The manifold directs gases into the exhaust, while the catalytic converter transforms certain pollutants. These are not the intake manifold or cooling radiator.
