and what ppl use for cut the pipe with that "form"?
-
Holesaw, die grinder, tube notcher.
-
probably a hole saw and layed on a pipe with a larger diameter and hammered

Get pipe that you plan to use for wastegate. Wrap a sheet of paper around it, tape it together to make a paper pipe.
Now take paper pipe off of metal pipe.
Push paper pipe against header where you want it to go. Cut the paper a little where it hits. Keep doing this till it fits perfect.
Once paper fits good, push it against header and draw a line around collector where it fits against. This line is what you need to cut.
Now drill a 1/4" hole inside the line you drew. Then up a size till it 1/2", then get a 1/4" carbide bur with an air grinder (20 bucks at harbor freight) to make the hole bigger till ti touches the line you drew using the paper pipe.

Works better with spagetti noodles and rubber bands. A tubing notcher is basicly a hole saw on a very ridgid axle that can be pushed in/out, driven by any drill you can fit. Very little deflection with a decent notcher. With coolant, the hole saw will stay sharp for a while.

the pipe i used for my waste gate was a 90* that i cut to fit, gave me a sweet swooping angled transition from the runners to the WG....
-
plasma cutter rough, burr to clean up
-
that wastegate branch looks like it is made from an elbow. i'd cut it with a plasma... but only after making the branch first, then drawing the outline onto the collector.
