An exhaust muffler for transverse installation in a vehicle includes a muffler housing (26) elongated in the direction of a housing longitudinal axis (G) with a housing jacket (28) and two front walls (30, 32). The two front walls (30, 32) are arranged at spaced locations from one another and define an interior (34) of the muffler with the housing jacket (28). At least one inlet pipe (36) leads into the interior (34) of the muffler and at least one outlet pipe (20) leads out of the interior (34) of the muffler. At least one front wall (30, 32) has at least one predetermined deformation area (50, 52).
