welcome to the board.

honestly, i'm not 100% sure what you're asking or trying to do, but i'm willing to work with you, get past our communication issues and see if i (or someone else) can get you the answers you need.

let me start with a universal tool we all can use, the FSM. you can get a copy of it from: Foxed.ca

also, what car do you have?

I'm going to go out on a limb and say it's a Turbo FC, based on the placement of the Air Bypass Valve compared to the Turbo Inlet Duct. Fairly sure he is referring to the ABV as the "Tube Wastegate". Also, based on the context clues, it's a safe bet that his Turbo Inlet Duct has cracked or split, he wants to go to a metal version of it but is not sure how to plumb the ABV Outlet Pipe and Vacuum Lines into it.

OP, can you take a picture of the MAP Sensor? Look for the Fuse Box, then go to the OPPOSITE side of the engine bay. This will tell us exactly what you have so we can assist you better.

I’m going to go on more of a limb and say OP has a s5 t2.

Item circled in red is the stock air bypass valve. You “need” this or another type or blow off valve to release the boost pressure when you step off of the gas.

you don’t necessarily “need” one but it keeps the turbo healthy as the turbo will not want to spin backwards due to the boost pressure.

the item in the bottom right black circle with the metal check valve is for the pcv system. It lets bypass gasses from the crankcase back into the system.

the item in the bottom left circle is the bleed from the turbo boost control solenoid. It bleeds air away from the wastegate until target boost values are met.
