Period Correct Exhaust Build

[1962300]

Who does what?
I am building a late 1940's style 1932 Roadster...with a Flathead and dual 97's.

I need to design the exhaust.
I have Red's Headers to start. (not as period correct as making my own, I know)
I am interested in knowing what anyone may have done to create a Period Correct Exhaust from the Headers on back...
- All pipes slip fit?
- System held by hangers and not welded to frame
(Anyone sell vintage style hangers?)

Thanks!
