New waste outlet needs to meet old pipe

[bricabraclady]

I have done a search, sorry if this advice is here somewhere. We are changing our kitchen sink, still having two bowls. Previous one had an S bend on each waste and then pipes joined ( in a sort of V formation) to travel vertically to below floor and then out of building horizontally. Thinking of using the Lira 11 set up (new Franke sink) but it discharges the u bend horizontally. Can another bend go in immediately after the trap to take the flow down the old outlet pipe? Seems odd they don't give the option of pipes vertical.

Thanks

The less bends the better, but if you have to put another then, do it
