A muffler comprises an outer shell defining a chamber, a baffle positioned in the chamber defined by the outer shell, and an inner plate positioned in the chamber. The inner plate includes a channel and a ridge coupled to the channel. The ridge extends away from the channel. The baffle includes an outer edge positioned adjacent to the outer shell and an inner edge positioned adjacent to the ridge and spaced apart from the channel.

[ What is claimed is:] [1.] A muffler comprisingan outer shell defining a chamber,a baffle positioned in the chamber defined by the outer shell, the baffle including an inner plate-receiving aperture, an outer edge positioned adjacent to the outer shell and an inner edge,a first inner plate positioned in the chamber defined by the outer shell, the first inner plate including a first end, a second end, a base, a channel coupled to the base, and a ridge coupled to the channel, the channel including an inner surface, an outer surface, a first portion positioned between the first end of the first inner plate and the ridge and a second portion positioned between the second end of the first inner plate and the ridge, anda second inner plate positioned in the chamber defined by the outer shell, the first and second inner plates being positioned in the inner plate-receiving aperture of the baffle, the second inner plate including a first end, a second end, a base, a channel coupled to the base, and a ridge coupled to the channel, the channel including an inner surface, an outer surface, a first portion positioned between the first end of the second inner plate and the ridge and a second portion positioned between the second end of the second inner plate and the ridge, the inner surfaces of the channels of the first and second inner plates cooperating to define a passage therebetween having an axis, the second portions of the first and second inner plates including a plurality of louvers having a base portion coupled to the second portions of the first and second inner plates and an outer portion spaced apart from the axis by a first distance, the outer surface of the channels of the first and second inner plates being spaced apart from the axis by a second distance that is less than the first distance, the outer surface of the ridges of the first and second inner plates being spaced apart from the axis by a third distance that is greater than the first and second distances so that the ridges are positioned adjacent to the inner edge of the baffle, the inner edge of the baffle being spaced apart from the respective channel, and each ridge including a stop that contacts the baffle to prevent movement of the baffle toward one of the first and second ends of the first and second inner plates.
