From the cats back, they are all Lego.
However the single cutout on your bumper means it won’t fit a dual exhaust unless you change the rear bar. You could of course cut your bar, though it’s going to look really “how ya goin’”. Get a SV6 or SS rear bar.
SV6 and Calais V6 had the dual single mufflers.
Exhaust size was the same as SS.
SS had two types of dual tip mufflers. One had a dummy pipe and an open one. The other type was a proper dual tip. They sound great on V6. Perfect sound.
Ute is unique to the ute and so is the wagon from memory. Differences in the end parts.
