Default Usdm exhaust on JDM car

Ok so I have a 2003 blobeye STI that arrives end of December, I have done some research and know that the jdm downpipe is shorter than the usdm downpipe.
Now I would like the apexi N1 exhaust because I feel it sounds incredible, now with everyone out there doing the jdm swaps.
Has anyone figured out the best work around to make this work ?
I have read something along the lines of adding length to the mid pipe, or going full usdm turbo back but it interfering with the steering rack ( cause jdm ).
So I figured I would ask here as most answers aren't very clear

Assuming the Apexi N1 is made for USDM STI's, you'd have to take it to a shop and have them lengthen the midpipe around 4-5inches to fit your JDM.

Also the USDM turboback systems won't work for your car, since you have the twinscroll turbo.

So, what are you trying to do?

You have a JDM 2003 STi and you want to put a complete USDM exhaust on it? Why?

You can use the JDM DP, whatever USDM catback you want, and go to a good muffler performance shop who can make you the connection piece, or make you the entire exhaust from the DP back.

I have a shop near me that does excellent work. They custom bend everything to fit nice and tight w/no rattles/bangs, and it comes out less expensive that off the shelf parts.

If you need a JDM catted DP, I have one in very good condition.

I was just looking at all the options so I could figure out the easiest way to do things as yes I want the apexi, but i hadn't found any answer that were very clear. But between you and the poster above I think I got it figured.
