The Hose Upgrade for the F30 will replace parts of the Turbo Outlet, to create a larger diameter for better flow, all while lessening turbulence.
Look at your parts for the Turbo Outlet Kit.
The FMIC Side Aluminum pipe and the coupler will both be replaced by the N55 Hose Upgrade for the hot side as shown below.
First you can put the Turbo Side Aluminum pipe on the turbo, and make sure the C-clip is fully seated in the race to ensure there is no boost leak at this side.
Slide the N55HU over the Turbo Side Aluminum pipe with a clamp as shown in the diagram.
Slide the other side of the N55HU over the fitting on the FMIC, and tighten down the clamp in the location as shown in the diagram below.
Now you have a full upgraded hotside piping for your charge air system!
