I am modifying my stock FM downpipe...well, I should put it more like, "using it for parts to build a different DP". I am going to use my Tial 38mm MVS wastegate, and also use a crank evac setup. I know the crank evac needs to be plumbed in after my O2, but does it matter where the wastegate dump goes?
The following is a photo of a BEGI DP that is used for EWG and has the O2 bungs pretty far down. The line with the text next to it is where I want to put my O2 bung (I only need 1).
What says MT.net about placement?

In other words "what comes out of the exhaust side of the cylinder head will have the same air fuel ratio if it passes though a wastegate or a turbine"?
