Abstract
An exhaust system for an engine having a plurality of combustion chambers includes a housing containing a first array of parallel positioned emission treatment devices and a second array of parallel positioned emission treatment devices axially spaced apart from one another. A first exhaust passageway is in fluid communication with the combustion chambers and contains the first array of emission treatment devices. A second and separate exhaust passageway is in fluid communication with the combustion chambers and contains the second array of emission treatment devices. A first valve restricts the exhaust flow through the first exhaust passageway. A second valve restricts the exhaust flow through the second exhaust passageway.
