That's exactly what it looks like. Only the longest tube on each header is done this way. Looks like they started with a J-bend and mandrel bent the other end on the rest. I'm guessing the straight part on the J-bend was not long enough to make the long tube in one piece. I understand cutting some time by purchasing J-bends for the places you can use them. But if you are set up with a mandrel bender wouldn't it be easier to make a double bend on a straight piece rather than slop two pieces together? They did grind the weld smooth on the outside so it looks pretty. AKA, whip cream on sh__
Thanks,

It looks to me like these are made from j-bends and not 1 piece bends. Eiether way, it's not really necessary to use a piece of tube on the inside. |
