I have access to an experienced licensed welder, but lack the resources for tube bending. Are there header "kits" out there that I could use to fab up some turbo headers? The generic kits I've looked at don't allow any real flexibility for building a turbo header. Is there prebent tubing that can be purchased that would allow me to fab up some turbo headers? I'm not looking for perfectly fabbed, equal length highly engineered headers here. As long as they are built well, built to last, and functional, I'll be happy. If I can find something like this, then I can put together a set of headers for nothing more then the cost of materials.
