An exhaust system for use with a combustion engine is disclosed. The exhaust system may have a passage connected to receive exhaust from the combustion engine, and a cooling device located external to the passage to create a thermal gradient across a flow area of the passage that causes particulates within the exhaust to agglomerate on a wall of the passage. The exhaust system may also have a filtration device located to separate agglomerated particulates from the exhaust.
