Armytrix exhaust-- which downpipe?

Thinking I'm going to bite the bullet and get an Armytrix exhaust for my Golf R. Already have Akrapovic on my other car so a bit spoiled with that type of sound. Other car is catless though and my family hates it so have to stick with cats on the Golf... anyone have experience with this? Can the AWE cat and res downpipe mate up perfectly with the Armytrix exhaust? Armytrix only offers a catless DP option.
I've tried some searches, but not a lot of up to date info... any advice is appreciated!
