As title states, I want one of these for my EVO III engine as pictured.
I'll give it a go for you.
I run my own custom engineering business. I am not an exhaust joint. Between myself and some mates, we can make just about anything out of metal- machining, welding, bending, forming sheet steel, etc.
Do you want show, or go on the cheap?
Can do in mild steel, mig weld (cheap$, some would say the best choice), 304, 316, or 321 stainless, purged TIG. Some limitations on the flex joint. Any coatings, you would have to organise.
I would also need a physical sample, shop drawing, or the car for a period of time- thats always a drama.
Looks to me like it could also benifit from some mandrel bends. And some flanges.
