SW Headers or full set up?

[Colt]

Looking at getting the SW headers, on their site it seems some stuff is changing or no longer offered.

Anyways, I want to see the consensus of the best set up for keeping the cats.

Should I just get the SW headers or get the Cats and mid pipe. I want to use other mufflers.

I know the older cats had issues, I don't know much about the newer high flow ones SW uses. Seems the headers, cats, and mid pipe would install easier than a custom set up.

Thanks.
