Well, I just sold the parts to make the 340 down pipe for $45 (plus shipping) to another member. That includes a section of "super tight" mandrel bent pipe, a 340 flange adapter (my last one) and a section of flat flared pipe for the 340 manifold. A section of super tight mandrel bent pipe, all by itself, will cost you $40 if you can find one?? When I used these parts on my Barracuda I placed all the pieces on the manifold (on the car) then welded it in place so that everything cleared. If I weld it up for you then the price goes up to $85 because it takes some time to do it off the car.
