Right here's how it works on an agu stock from memory
Turbo 50mm->90degree silicone bend->steel charge pipe with 90 degree mandrel bend (with 8mm outlet for n75 and 25mm outlet for DV recirc)-> this then becomes all mainly silicone and connects to->pancake pipe->SMIC->more silicone all the way to->TB->Inlet manifold->Engine *tada!*
If you need the 8mm T pieces for whatever reason, cheapest tip is, if you are not planning to ever remove the FMIC once its on, then get that charge pipe off the back of the engine which you would need to unclamp with 10mm socket if memory serves me well, I did it from underneath the car as you have silicone joining onto it as well. Once its off you have the 25mm and 8mm bits branching off it. Chop it down with an angle grinder and get it beaded and wollah you have a brand new 8mm T piece from a recycled charge pipe, or go scrappy and dig spare charge pipe out.
You won't be able to chop out the 25mm T piece, as its very close to the bend, this is providing you want a straight T piece, or technically you could re-use that charge pipe before the TB as it will allow the DV to be relocated, but I'm not sure how the n75 would respond to a feed that far in the system.
Route wise, i'd say as Toph said, whip the bumper off have a quick fiddle and decide how you want it done, there's many ways possible and its down to you, plus with the bumper off you will get an idea of how much piping there is and how it can go with the amount of piping you have in front of you.
