ABSTRACT:
A support arrangement for an exhaust system including an upright muffler and an upwardly-extending exhaust stack located behind the cab of a truck. An arm is mounted on a frame member of the truck, and a vibration isolator supported on the arm in turn supports the weight of an exhaust pipe elbow, a muffler, and a stack located above the muffler, all oriented generally upwardly. A pair of links are attached to the exhaust stack and to a mounting fastened to the back side of the cab to support the muffler and stack with respect to longitudinal and lateral movement relative to the truck while still permitting vertical movement of the cab relative to the frame.
