Re: Old Exhaust Shower Head
Has anybody tried to do any welding on one of the originals (since 1975 i mean)? If I could match the alloy with the appropriate filler rods I might just try to make repairs to the ones I have since I can be pretty handy with a TIG torch.
Still wouldn't mind finding an old one lying around somewhere that I could use as a template though."The only thing that always works on an old boat is the owner" - Some Wise Guy

As I understand it, the problem isn't just the holes you can see...it's the thin spots that are going to become holes as soon as you put heat to it. Or, they'll become holes shortly after you reinstall it. Once a liquid-holding or pressure vessel develops leaks, it's pretty much done.

It looks like D'Angelo uses 12 gauge stainless for the hot sections.

Re: Old Exhaust Shower Head
Is it necessary that the water jacket extend all the way to the back of the turbo or would a design with a water collar at the distal end of the elbow just above the shower head be sufficient for exhaust cooling? The remainder of the elbow would be encased in a blanket or hard coating.
Anyone have any thoughts on this?
Thanks

Re: Old Exhaust Shower Head
The reason dry stacks with wet showerheads are considered an upgrade is because water jackets eventually fail, taking out turbos and engines. I don't understand why anybody would go through the effort of making water jacketed risers when dry stacks are easier and better.
YMMV
That said, the link I posted a while back and other exhaust-related articles on my blog show how D'angelo does it. I used the same approach. Make it so water absolutely cannot get back into the engine, and you've done it right.
