So recently I purchased a ArmyTrix exhaust for my 2016 bmw 528i i was looking at the instructions and saw I needed to splice into a vacuum source. I don't think the 2016 has the vacuum source since it has the ewg. Is there anywhere else I can splice into? Or can i just ignore it? I'm pretty sure the exhaust uses the vacuum lines to open / close.

It does use vacuum for the valves. Mine pulls from under the intake manifold on the drivers side of the engine, not on the passenger side like you are showing in the diagram.

I'm not sure if there is one on the 528i do you think I would be able to pull from the brake servo or wastegate solenoid

You should be able to pull vacuum from wherever there is constant vacuum, the solenoid will open and close and adjust the valves accordingly.
