A die body apparatus (101) includes a first discharge member (105) configured to be bonded with respect to a base member (103) such that aligned elongated openings (209) of the base member (103) and first discharge member (105) provide a plurality of elongated feed passages placing a plurality of feed holes (106) of the base member (103) in fluid communication with a first honeycomb network of discharge slots (415) of the first discharge member (105). In further examples, methods of assembling a die body apparatus (101) includes the step of bonding a selected discharge member (105) of at least one discharge member with respect to a base member (103). In further examples methods of extruding batch material into a honeycomb body includes the steps of bonding a selected discharge member (105) with respect to a base member (103) and extruding a quantity of batch material through the die body apparatus (101) into an extruded honeycomb body with a honeycomb network of channels.
