Your best bet is to simply go to a muffler shop that handles MagnaFlow products and have them figure it out. That's what Dubbed did (I've seen his setup in person). And I have to warn you that just replacing the rear mufflers will make your CTS a bit loud...maybe too loud? This is probably the reason CORSA adds another muffler (x2) after the factory resonator.
