02 blazer ls 4d 4x4

I'm looking for...well it says it in the title. I was wondering if anyone knows of any i saw that thrush makes them but can only find it on 1 site and it's $15 more than without the flange. So what I'm looking for exactly is a glasspack with the 2 bolt flange already attached or a coupleing piece that has that 2 bolt flange. I'd really like to not hack the pipe between the cat and flange for the muffler if i can help it. I've done the infamous search for a thread with this type of question and it was nowhere to be found unfortunetly. Any help would be much appreciated. I was told no to straight piping so this is my next best option or so i think lol. Please help me or lead me to something that could be helpful. I'd rather not take it to the shop all because I have the resourses to do this job...or I thought i did. This stupid flange piece (which I've never encountered before past the cat in any other muffler swap I've done before) is the only thing stopping me. Thanks in advance.

 

Thrush Muffler Glasspack Direct fit - JCWhitney this is the one i found I'm not too sure about it because it doesn't say buy anywhere. Has me a little uneasy

 

I was going to say Look up "purple hornies". Its a glasspack made by flowtech. they come with a flange, but its a 3 hole. maybe you can call and see if they make a 2 hole flange style for it.
