The ones I just put on are dual tips, look at the pics of the blue C5 earlier in this post. I'm guessing thats what your talking about. Hope this helps.

I had my XSPower catbacks installed Friday and I be liking 'em. I was getting kinda annoyed that my wife's stock Yukon sounded better than my car 
But all is good now! I am glad though that I had a local shop install it. They did have problems with the provided clamps (one broke and one stripped). They tried some clamps they had and they were still concerned that it wasn't tight enough so they went ahead and welded a bead where the muffler connects up to the pipe. Attached are videos before and after. I took them with my phone so ....... but you can still hear the difference.
