Abstract:
An exhaust system baffling apparatus comprising:a tube; a plurality of radially extending flanges mounted in surrounding relation about the tube, wherein the outer edges of the flanges have a contour which generally corresponds to a contour of an inner surface of a wall of an exhaust pipe, wherein each flange includes a radial slit which extends from the tube to the outer edge of the flange, wherein opposed portions of the flanges adjacent the slits of the flanges are spread apart in opposite directions that are parallel to a longitudinal axis of the tube, wherein the opposed portions of the flanges adjacent the slits are angled in opposite directions and extend radially from the tube at non-perpendicular angles with respect to the tube, wherein the slits of at least two of the flanges are orientated at different angular positions around the longitudinal axis of the tube, wherein at least two of the flanges include brackets adjacent the outer edges of the flanges, wherein the brackets are adapted for securing the apparatus to an interior portion of the exhaust pipe.
