Look at your parts for the Turbo Outlet Kit.

Step 2

The FMIC Side Aluminum pipe and the coupler will both be replaced by the N55 Hose Upgrade for the hot side as shown below.

Step 3

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.

Step 4

Step 5

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.
