Abstract
An exhaust device includes a housing, first and second pipes, and a spacer. The first and second pipes are at least partially disposed within the housing. The first and second pipes include respective first and second surfaces. A portion of the second pipe is disposed inside the first pipe. The first and second surfaces cooperate to define an annular volume into which the spacer is disposed to prevent direct communication between the first and second pipes. One of the first and second pipes is fluidly connected to an exhaust gas inlet. The other of the first and second pipes is fluidly connected to an exhaust gas outlet. One of the first and second surfaces defines a radial indentation. The other of the first and second surfaces defines a radial protrusion. The spacer is disposed at least partially within the radial indentation and is in direct communication with the radial protrusion.
