The rear section has two inlet and outlet pipes welded to a muffler. A polished stainless steel finisher is installed on each of the outlet pipes. Three suspension rubbers connect hangers on the muffler to hangers and a bracket on the underside of the body.
The muffler consists of upper and lower shells, which contain inlet pipes connected to SAM (semi active muffler) valves, and perforated inner pipes supported in five baffle plates. The inner pipes connect to the outlet pipes.
The SAM valves vary the tone of the exhaust to give a more sporty sound at higher engine speeds. The SAM valves are normally closed, spring loaded check valves.
The SAM valves are non serviceable and the muffler is replaced as a complete assembly.
