A method of removing soot from soot-laden exhaust gas with a honeycomb body, the method comprising:

• flowing the soot-laden exhaust gas through large channels and small channels of the honeycomb body, wherein the large channels have a hydraulic diameter greater than 1.1 mm, the small channels have a hydraulic diameter less than 1.1 mm, and the large channels and small channels, taken together, have a geometric surface area greater than 2.9 mm1;
• and
• wherein at least some of the large channels act as bypass channels.
