Or you could do what I did, and save the cats. With the really nice clamps ACM provides, you can just throw the cats back on for the emissions test, and then swap back out.
My dealer did the ACM test pipe install for me, and only charged me like $75. So to just swap them back and forth, I'm sure they'd just charge $50 total.
