Abstract
A method is provided for manufacturing a heat shield for an exhaust system component. The exhaust system component preferably is of tubular nonlinear configuration. The heat shield is formed from a larger pipe having an internal diameter greater than the outer diameter of the exhaust system component. Appropriately dimensioned inwardly directed supports are formed in the larger pipe. The larger pipe then is bent into a nonlinear configuration substantially identical to the configuration of the exhaust system component. The outer pipe then is cut longitudinally in half along its entire length to define a unitary nonlinear heat shield which can be mounted to the exhaust system component. A portion of the remaining half of the larger pipe can be reattached to the heat shield to provide an air gap pipe along a portion of the length of the exhaust system component.
