ABSTRACT:
Hanger systems are provided for securing exhaust systems to the undercarriage of the automobile. One such system includes a hanger that incorporates an arm, a bushing defining an orifice, a retaining member, and a flange. The orifice receives a proximal end of the arm, which is loosely retained by the bushing so that the arm is able to rotate. The retaining member engages an exterior surface of the bushing and is formed, at least partially, of a strip of material. At least a portion of the strip of material is shaped to conform to at least a portion of the exterior surface of the bushing. The flange extends outwardly from the bushing. So configured, the hanger mounts to the automobile by attaching the flange to the frame member. The arm can be secured to a portion of the exhaust system so that the exhaust pipe is securely retained. Methods and other systems also are provided.
