How to repair downsprout section

OK this one is a little hard to explain, but basically there is a "super gutter" above in a valley section of the roof and it drains into a downsprout. The downsprout extends about 10 inches down then turn 90 degrees for about 4 feet, then turn 90 degrees again to connect to a straight section of a downsprout which leads into the foundation and eventually drains outside on the other side of the house.

I removed a section of the soffit to expose the two 90 degree sections. As you can see, I have two of these one on the left side and one on the right side of the interior courtyard.

I have always wonder why draining was so slow, and now I understand with the two 90 degree elbows it is just not flowing fast enough. Furthermore leaves and debris often gets washed into the downsprout and further slows the flow.

So I am installing two mesh screens at the top of the drains.

However the two 90 degree elbows must be adjusted. the almost horizontal piece of the downsprout is also corroded and broken (see the red circle area). My plan is to attach a new piece but give it a better slope. However I cannot find a replacement downsprout. These measure 6"x4.5" and was welded together (built in 1972). I do not see any downsprout with that size. Any suggestions what I can do there?

Thanks,

Call a guttering service and tell them what you need. A full service shop should be able to make any profile you need. If you have enough height, perhaps you could replace the tight elbows w/ sweeps. At the worst, forget the horizontal run and bring it out underneath the soffit and make the lateral run have sufficient slope to carry the water. May not be ideal visually, obviously so whether you can do so and maintain the aesthetics may limit choices...

BTW, usenet is a text medium so whatever you used to post pictures doesn't work for anybody to see -- need to either find a binary group (and many servers don't carry them so that's not universal or use one of the many free hosting sites). I kinda' remember a discussion on this funky drain system from some time back so have a clue of what you're talking about...
