Exhaust System parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Exhaust Manifold 1× Cast or fabricated header that collects exhaust gas from the cylinder ports into one pipe.
2 Catalytic Converter 1× Ceramic monolith coated with platinum-group metals.
3 Muffler 1× Chambered steel silencer in the exhaust line that reduces engine noise.
4 Exhaust Pipe 1× Steel tubing that carries exhaust gas from the manifold through the catalyst and muffler to the tailpipe.
5 Exhaust Hanger 4× Rubber isolator that hangs the exhaust from the underbody.
6 Exhaust Clamp & Gasket 4× Band clamp and gasket at each joint of the exhaust system.
7 Heat Shield 5× Stamped aluminium shield between the exhaust and the floor, tank or lines.
8 Oxygen Sensor 2× Lambda sensor before and after the catalyst that reports exhaust oxygen to the engine controller.
