Heat Shield: Testing and Inspection

Sound Insulators and Shields
Sound insulators and shields attached to the underbody protect the vehicle from exhaust system heat and should be inspected at regular intervals to ensure they are not dented or out of position. If a sound insulator and shield is damaged or shows evidence of deterioration, it should be replaced. The sound insulators and shields for the muffler, muffler pipe, resonator, and TWC pipe are installed separately.
