Most all of us know the early Elans came equipped with an oval intermediate exhaust pipe for more ground clearance. I would like to manufacture one for an early Elan I am restoring. It has no exhaust but it still has its original cast iron exhaust manifold. I am currently attempting to reproduce the original down pipe with the integral resonator. The information I'm looking for is the dimensions of the oval intermediate exhaust pipe. If someone still has one they would like to sell, please contact me. Or can someone provide measurements.
1) Total length of the intermediate pipe?
2) Length of the front portion to the kink?
3) Pipe diameter ID or OD?
4) From the front and from the rear of pipe, how many inches to where the pipe becomes oval?
5) Thickness or height of pipe where it is oval? So I know how much to crush the pipe. I'm assuming (that always gets me in trouble) the pipe is round at both ends ad is only oval within the center. Correct?

One place substantial road clearance was increased was in the header section of the system, including the "Y" pipe. I converted the hydraulic clutch release system from and external slave to a concentric slave within the clutch housing. This permitted the removal of the cast ring that formally held the external slave cylinder to the clutch housing. This allowed the even larger diameter pipes, including the "Y" pipe to be raised above the cross brace and the bottom of the chassis. The exhaust system only now drops below the bottom of the chassis where it passes beneath the chassis just aft of the gearbox.
