Abstract: A muffler for an exhaust system has a muffler housing with an inlet chamber fluidically connected an outlet chamber. The inlet chamber has an inlet pipe for supplying an exhaust gas stream into the inlet chamber, and the outlet chamber has an outlet pipe for discharging the exhaust gas stream from the outlet chamber, wherein the inlet pipe and the outlet pipe each have a first pipe portion and a second pipe portion. The inlet pipe and the outlet pipe in the respective first pipe portions are circumferentially impermeable to the exhaust gas stream and are circumferentially porous in the respective second pipe portions. The first pipe portions each have a predetermined length, such that a ?/4 resonator is formed between the respective first pipe portions and walls of the muffler housing associated with the respective first pipe portions.

Abstract: A lighted display field for writing, symbols or the like, is provided on a wall part, for example, a door entrance strip of a vehicle. The wall part includes openings forming the writing or the symbols. A luminous foil is mounted on the covered side of the wall part and is visible through the openings.
