I have that same setup with dougs headers. All I had to do was take the x-pieces to a muffler shop to get them expanded and make 'em a slip fit, and then loosely assembled it, tacked it, and took it out and welded it. I need to re-do the rear hangers though.
I can possible get pics for you in a week or two if you aren't in a rush, but it's under a foot of snow at the moment.
