    I don't have XS-power but you need to make sure you trim the flange, and make the holes bigger, I had similar issue with another make, to make life easier for yourself, make sure after you take it off the flange and the holes of the xs DP are exactly the same as the standard one, otherwise you will spend an entire day back and forward, as to fitting it to the standard cat-back, I don’t think it is an issue. They are designed to go on your car then they would fit in the middle.
