Hi Mike it looks great I see the one side sits on the header so I'm assuming that the other side does as well right? If it does then your in good shape. All you have to sister up is the width of the base of your cabinet. You don't have to go beyond that. Nail them together or put spacers in between every 16" and nail both side to the spacer ( spacer= a piece of 2x4 the height of the joist installed vertically every 16").
