Your best approach may be to cut out the centre section of your air dam by a few inches and curve your undertray up to match like you show with the yellow line.
my stock air dam is way to short. im thinking about adding bits of chloroplast to it where its infront of the tires. the chloroplast will be angled following the air dam so the air is deflected out away from the wheels
