We gutted my cats a few weeks ago to avoid future problems. I am sure the Vengeance guys have been saying that they have seen a lot of cat issues on FI cars as of late.
I am fortunate to live in a state with no visual and no emissions inspections so I just gutted mine, you may want to remove and replace with a test pipe so you can re-install at test time.
