Design as in using something like CAD? Here's a long shot, I was going to "design" my own headers once, my plan was -

1. Buy corrugated plastic tubing from the hardware store in the diameter I intended to use.
2. Cap the end off at the head and and then snake it around until I got the fit I wanted.
3. Once I had it, hold in place with tie-wraps and spray expanding foam into the other end.

Once the foam sets, my "mock-up" pipe would be non-flexible and I could remove it and have someone make up the real deal. Never tried it but think it would work.

Disclaimer: Many things I thought would work have failed miserably
