I would recommend JP Exhausts. There is a link on the site somewhere.

The can supply mandrel bends in a variety of diameters and radiuses (Radii?)

All manufactured in house to your spec. They also do the dairy bends.

In fact there is not much they don't know about exhausts.

I have always had good service from them however they are short of a manager in the manifolds department at the moment so i think they may have a longer lead time than usual.
