An exhaust processor is provided for filtering particulate matter from a combustion product. The exhaust processor includes a partition situated inside a housing to form a filtering region and a bypass region in an upstream portion of the housing. A substrate is mounted in the filtering region for solid particle filtration. A muffler is situated in a downstream portion of the housing spaced apart from the partition so that the entire spacial volume of the muffler can be utilized by combustion product passing through either the filtering region or the bypass region.
