ABSTRACT:
An exhaust control device includes a wear indicator disposed within a housing of the exhaust control device. The wear indicator is arranged to be exposed to a flow of exhaust gas through the exhaust control device. The wear indicator has a first observable state indicative of remaining useful life of the exhaust control device. The wear indicator is responsive to a flow of exhaust gas through the exhaust control device to assume a second observable state indicative of the exhaust control device having reached the end of its useful life.
