Exemplary semiconductor processing systems may include a lid plate and a gas splitter. The gas splitter may be seated on the lid plate. The gas splitter may include a top surface and a plurality of side surfaces. The gas splitter may define a gas inlet, a gas outlet, a gas lumen that extends between and fluidly couples the gas inlet with the gas outlet, and a first divert lumen that is fluidly coupled with the gas lumen and that directs gases away from a processing chamber through a divert outlet. The semiconductor processing system may include a first divert weldment. The first divert weldment may extend from and fluidly couple to the divert outlet. The first divert weldment may include a first divert weldment outlet and a second divert weldment outlet.
