Abstract
A vehicle exhaust system component assembly includes a first exhaust component defining a first center axis and a second exhaust component downstream of the first exhaust component and defining a second center axis that is spaced apart from and generally parallel to the first center axis. The first and second exhaust components are spaced apart from each other by an area. A plenum is positioned substantially within the area, and has a first end connected to the first exhaust component and a second end connected to the second exhaust component. The plenum is defined by a non-uniform cross-sectional shape as the plenum extends along a length from the first end to the second end. A doser is mounted to the plenum and is configured to inject a reducing agent to mix with exhaust gases within the plenum.
