I've seen a lot of people building their own but does anyone sell one in 304 SS? If not is there anything I can read up on cutting & fitting pipe angles? I have searched here and on some other forums and websites and cant really find anything pertaining to this subject. TIA

There was a place that sold a merge but it was for a round flange. I couldn't find the site, I think it was on my old computer.
Anyway I prefer to make my own because I think it will out flow the round flange. I slice the pipe almost in half, and almost vertically then start shaping it square with a mallet. I fit it in the flange and squeeze in the corners with a set of narrow vice grips. Then I start on the other pipe. I use a grinder to get the gap between the two pipes just right then weld.

Thanks, I havent had time to read it entirely but about the only thing that I could tell that was missing from it was how to shape the merge into a rectangle the size of your turbo flange. If you have anything you'd like to add I'm all ears & eyes. Can use all the tips,trick's,& input I can get.

The only problem with buyin one is the piece will be taller then need be. If you build your own you can make it more custom/fit where you need it, and get your wastegate in a better spot.
At first i bought a piece for a t4 flange, and we made 2 2.5's go to it.
Im sure it could of been done nice, but we ended up just cutting 2 90's and having them come into the t4 flange.
best pic i have of what we made.

We had 0 experience with metal fab or welding before doing this. We figureded it out as we went.
