Exhaust System: Description and Operation
DESCRIPTIONPeriodic maintenance of the exhaust system is not required; however, if the vehicle is raised for other service, it is advisable to check the general condition of the Three Way Catalytic Converter (TWC), pipes and muffler. Check complete exhaust system and nearby body areas for broken, damaged, missing or mispositioned parts, open seams, holes, loose connections or other deterioration that could permit exhaust fumes to seep into the passenger compartment. Dust or water in the rear compartment may indicate a problem in one of these areas. Any faulty areas should be corrected immediately. The exhaust system consists (from front to rear) of an exhaust manifold, a Warm Up Three Way Catalytic Convertor (WU-TWC) (if equipped), an exhaust manifold heat shield, a front pipe/TWC assembly and a resonator/muffler/tail pipe assembly. Various flexible rubber hangers suspend the system along the underside of the vehicle.
