Material in turbo headers.

[Espen Hilde]

Hi!
I have made turbo manifolds from prebent 90degrees steam tubes and
straights.
It works great.
I would have liked to take same length straight tubes and weld the openings
and fill it with sand ,bumb it so it settles .Use heat and bend away.If you
have been a plumber you probably know this prosess.....
