1. A honeycomb body comprising:
a plurality of intersecting porous walls comprised of a plurality of radially-extending walls and a plurality of circumferentially-extending walls, wherein the intersecting porous walls are comprised of a porous ceramic material;
a central region centrally located on an end face of the honeycomb body;
wherein at least some of the radially-extending walls extend continuously from the central region of the honeycomb body to a peripheral skin of the honeycomb body;
wherein the plurality of radially-extending walls and the plurality of circumferentially-extending walls form a plurality of circumferential zones of cells; and
wherein the plurality of circumferential zones of cells comprises:
a first zone of cells comprising two or more circumferential rings of cells, each of the two or more circumferential rings of cells of the first zone of cells having a first cell density; and
a second zone of cells comprising two or more circumferential rings of cells having varying cell densities across the two or more circumferential rings of cells.
