Either way is fine. There is no performance advantage to either method.
However - if you run the wastegate outlet into the turbo exhaust downpipe, the wastegate has better support of its weight and will be less prone to cracking at the wastegate inlet flange connection.

Can't the gases from the wastegate interrupt the gases from the turbine if it connects to close and in a too steap angle?

That one doesn't look like a Gonzo group hug, it is SWEET!

Anyone know anyone around the Ramstein/Landstuhl area with a T4?

I love the looks of that header. This flanges all around. Will that come up from in front or behind the engine?
