Abstract: A vehicle exhaust system and method of minimizing a leaked mass flow 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. The reservoir volume and inlet area having a defined relationship. The reservoir volume and a mass flow through the inlet area having a defined relationship.

Abstract: A vehicle exhaust system having a first pipe, a second pipe, and an integral hood. The first pipe extending between a first end and a second end. The second pipe extending between a third end and a fourth end. At least a portion of the first pipe being positioned within the second pipe such that the second end is provided downstream of the third end. The integral hood is formed between the second end and the third end.
