Not sure how you were looking but I entered for a 2003 Yukon 1500 with a 6.0 engine and there they are, catted and non catted.
Edit: I went back and read that yours is a 2005 but the ones I linked are for 2001-2006 so they will work for you.

for some reason when viewing their page from my phone is only showed the headers. when viewing from an actual computer, i see both headers and connection pipes. thanks for the help on this.

You will make zero power over cheap headers with kooks. Do you just have money burning a hole in your pocket? Jeez send me some.

looks like i may need to make a decision sooner rather than later. Towing the SXS over the weekend i had a p0101 code pop up a couple times. i have a spare maf i can toss in, but in my experince, that that code at high load and high rpm is usually cats starting to clog up.

i will dig more into it this weekend when i have more free time.
