One will need a 3" cat-back and the other a 2.5" cat-back.

Thing is I think most of the 3" cat-backs still have a 2.5" inlet. From my understanding you have to buy a matched up system like TSP, KOOKS, or LG. ARH has a 3" that goes all the way back to the axle but there aren't many 3" axle-back systems.
