I currently am running my own cat back with turn down before the rear axle. I cut the pipe off behind the cat and added a 2.5" pipe with 2.5" small welded chamber muffler. I know that helped flow considerably as the pipe behind the last cat used to keck-down to 2".
I did a quick search, looked at a few pages of results but I did not find what I want and it's got to have been done??? I want to legally increase flow if there are gains to be had. The stock set-up looks to be restrictive with multiple cats???
