Templates? Do you mean for pipe design? If so there are plenty of programs out there that can assist. Fairly easy to learn if you are planning on going to all the trouble of welding your own. Suggest starting there. I have not personally seen plans floating around and they will depend on what you are looking for in a pipe.

It was to great help but I still need those degrees to get the correct sizes of the expansion chamber. I have a program but don't have the knowledge to get the correct degrees. :smt017

If you have the ability, stop sweating it and dive in. Practice goes a long way. All the great pipe makers learn from trial and error, even with good specs. Find something, and go for it.
