Each cat should be separately serviceable on the SRT-6. Personally, I would simply replace them with 200-cell versions and gain a horse or two.
Does the state law require you to use OEM parts? Or can you simply replace with an aftermarket, as long as the total cat-count on the car matches the factory specs?
What I have form this site and what the dealer is looking at by the vin are the same parts and pictures.
