afaik most of the sound comes from the tires, not necessarily the engine or the exhaust. obviously not the case for every car, but for most commuter cars it is. the faster the tires are rolling, the louder the sound.
i think at higher speeds the wheel and road noise drowns out the engine noise, but at lower speeds its the engine, especially during acceletation.
in the region of 20-30mph i’d think the engine is probably the louder part.
