A fluid-conduit collector spans across a plurality of collector-inlet interface structures and at least one fluidic diode element. A branch inlet portion of at least one collector-inlet interface structure, in fluid communication with a corresponding fluid-conduit runner portion, provides for receiving exhaust gases from a corresponding separate exhaust port of an intermittent-combustion internal combustion engine. A main inlet portion of the collector-inlet interface structure in fluid communication with an outlet portion thereof defines a portion of the fluid conduit of the collector. The branch inlet portion is in fluid communication with the outlet portion via a collector inlet port that is at least partially bounded by a relatively-sharp-edged junction with the fluid conduit of the collector. The fluidic-diode element located coincident with, or downstream of, the collector inlet port provides for a relatively-higher coefficient of discharge for exhaust gases flowing towards an outlet of the collector, than for an associated reverse-directed bulk flow or acoustic pressure wave flowing in a reverse direction.
