1. A vehicle exhaust system comprising:
an exhaust component defining a central axis and having an inner surface and an outer surface, such that the inner surface defines a primary exhaust gas flow path extending along the central axis from an inlet to an outlet; and
a surface component having a hood spaced from the exhaust component to define a reservoir having a reservoir volume (V), the reservoir comprising a reservoir inlet fluidly coupled to the primary exhaust gas flow path and defining an inlet area (A), and a reservoir outlet fluidly coupled to an outside environment;
wherein fluid traveling along the primary exhaust gas flow path and through the reservoir inlet defines a diverted flow (DF) and the hood holds the diverted flow (DF) within the reservoir;
wherein the hood enables the diverted flow (DF) to change direction at least once within the reservoir; wherein the diverted flow (DF) flows through the reservoir in a first direction and a second direction opposite the first direction; and
wherein a minimum reservoir volume (Vmin) to inlet area (A) ratio is greater than or equal to
