The top pipe is an original y pipe for a 36 to 40 big twin muffler. Notice how the inlet for the rear header pipe has such a nice saddle to it. This feature is very difficult to copy. The pipe below the og pipe is a nineties and earlier replacement. Notice how the pipe is filleted and then welded to the bottom pipe. The saddle below is a Dennis Corso CO. saddle, this is what is on most of the y pipes that you buy from v twin or J and P or anyone else. I remember when Dennis came out with these circa 98 ish. Everyone went nuts, it was honestly the best thing since sliced bread. They are pretty damn close, but still leave a little room for improvement, which brings us to the saddle below it---- my first prototype saddle!!!! This is a corso saddle with a skirt welded on to it. The mystery part from last week was the skirt. It is still in prototype stages, and I will probably end up having to make it a little bigger, but it is the next step in making the saddle closer to the original style.
Here is a picture of the inside before metal finishing. This took about an hour to do, which is a long time for such a minute detail. Life was a lot more simple when I just relied on other people to make parts and before I knew how to manufacture stuff.
