Dual exhaust conversion
 

Has anyone done a dual exhaust conversion on a 60 Olds Dynamic 88? I realize that the same manifold on the dual side is used for all 60 Oldsmobiles. I just can't figure out how the pipe comes down from the manifold, gets through the narrow space below, and makes the tight twists and bends to get back to the hole in the frame that it eventually goes through. Did somebody actually design this???

If somebody can tell me that they have done this and just how the pipe gets through the narrow space and makes the tight turns I will believe it is possible.
