You will also need the inner plate, its very similar to a T1 inner if you can find one

Sorry, I got busy working on my Molinari and forgot to check back on this thread. I measured the set of pipes in the picture above. Here are the dimensions.

Cones: 2" small diameter - 3.75" large diameter cone length = 14"
each cone has 2 triangular strength pieces welded to them (top/bottom) that have a 1.5" base and are approx. 6" long
The cone material is 0.045" thickness

Elbows: These appear to be cast - the dimensions are approximate. The ID = 1.5" and the OD = 1.875". Their centerline is 3" above the plate surface. They grow in diameter as they approach the point where the two runners merge, just before where the cone is welded. These will be hard to fabricate from scratch!

Plate: The plate is approx. 21.5" x 5.5". There is a wider point 5.8" towards the bottom to accommodate a water hole. The plate thickness is approx. 0.225" The exhaust openings are 1.5" diam. The paired openings are 3-1/8" on center and there is 1-7/8" space between the bottom of one pair and the top of the next pair. The center spacing from the top of the plate are approx: 2.5", 5-5/8", 9", 12.5", 15-5/8", 18-7/8"

Hope this helps. I'd suggest advertizing on this site and hydroracer.net for a set of these pipes. Tim Kurcz is still producing Parker pipes (I think they are Parkers). Regards, Roger Hinsdale

Here's a picture of a 4-cylinder set of Parker pipes from Tim.227661
