Abstract
An exhaust system for a vehicle may include a tailpipe and a collar. The tailpipe may be adapted to receive exhaust gas from an internal combustion engine and may include an outlet. The collar may include an inner surface, an outer surface, an air-inlet, and an air-outlet. The inner surface may be radially spaced apart from the tailpipe and may at least partially surround the outlet of the tailpipe. The inner and outer surfaces may be shaped to form a profile that causes a first air-flow to accelerate upon flowing between the inner surface and the tailpipe to a first velocity that is faster than a second velocity of a second air-flow. The second air-flow may be flowing adjacent the outer surface and radially outward relative to the outer surface.
