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.
