Obviously this may not work for all mufflers, as most systems seem to have different sizes but it should work in most cases.
For those looking to do this mod in the near future, I'd suggest getting in good with an exhaust shop and having them make you a custom catback that's ready for an extra cat to be added. Could end up being cheaper than buying a full cat-back and having to modify it.
yeah a custom would be better, but for the $500 fswerks stealth and just swapping the rear muffler with the cat and adding a foot or so of pipe would be the most cost efficient method without cutting any of the fswerks parts to make space for the muffler. That could be fully done for $700 including the cat and extra piping.
