2015 3.6L Cat Back Question

After looking for a month or so i think the sound of the pypes kit with the street pro mufflers is by far my favorite. I'm pretty sure it should fit the RWD '15s (even though it's compatibility is listed '11-'14) but i'm curious as to whether it would fit an AWD model. Does anyone know if the downpipes are different? I emailed the guys at pypes and they have no idea either.
