I installed the Perrin Inlet on my 2005 Outback XT today.

The problem is not the inlet and it does not need to be cut.

The issue is that originally Perrin made a PSP-420 Inlet and now its PSP-421

The original one was made for the legacy and the newer one is now made for the 08 Up WRX.

They are identical with one exception, the BOV tube connection is more toward the front of the car.

Unfortunately perrin quit making the one that fit better on the legacy for the one that fits better on the WRX. More demand for the WRX and they are similar so why make both.

The key to putting this on a legacy I found out today is using the WRX BOV tube.

The WRX BOV tube that connects to the inlet has more of a bend in the end where it goes on the inlet.

That bend, bends more toward the front of the car. This is the reason for the Change in the Perrin Inlet.

I just happened to have a whole 08 UP WRX intake manifold with everything still on it.

I took the BOV tube off the WRX inlet/manifold and it fit perfect on my Outback XT with Perrin Inlet.

So bottom line is to make the Inlet line up better just get a WRX BOV tube and you are good to go.
