  • Patent number: 7726444
    Abstract: An exhaust system baffle is provided comprising a tube and a plurality of radially extending flanges mounted in surrounding relation about the tube. Each flange includes a centrally positioned aperture and a slit that extends through the flange from the aperture to an outer edge of the flange. The tube extends through the apertures of the flanges. Each flange includes a first edge portion that bounds a first side of the slit. Each flange includes a second edge portion that bounds a second side of the slit opposite the first side of the slit. The opposed first and second edge portions of each flange are bent such that the opposed first and second edge portions are orientated to extend outwardly from the tube at angles that are each acute in opposed directions with respect to the central longitudinal axis of the tube.

  • Patent number: 7374017
    Abstract: An exhaust system baffling apparatus is provided. The apparatus includes a tube with at least one end that is not open. The apparatus further includes a plurality of C-shaped flanges in surrounding relation about the tube. 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. Opposed portions of the flanges adjacent the slits of the flanges are spread apart along the tube in a longitudinal direction. In addition, the opposed portions of the flanges adjacent the slits are angled in opposite directions and extend radially from the tube at a non-perpendicular angle with respect to the tube. 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.
