As I read your post, I concluded that it was your intention to run a second
pipe inside the existing pipe and through the body of the cat ... rather
than do that, I'd just cut the existing inlet and outlet pipes off and run
your sleeve through the existing holes (enlarging them, if necessary) and
either recycle the old mounting flanges or weld on new ones.  It shouldn't
be that difficult to do and will still look OEM...

True ... but why step down the pipe size at all?  Every little bit helps...
