Abstract
An exhaust processor is provided for filtering particulate matter from a combustion product. The exhaust processor includes a housing providing a main passageway having a substrate mounted therein for solid particle filtration. The housing also provides an auxiliary passageway containing a muffler for attenuating noise of combustion product. Combustion product is diverted through the auxiliary passageway after the substrate collects a predetermined amount of solid particles from combustion product to permit regeneration of the substrate by a burner.
