Any thoughts on a secondary cat delete?

Had done this on my c63 and it actually sounded great. No CEL or smell, and still passed emissions. Since the valves are such a big obstacle just wondering why no one’s talked about a cat delete much yet.

My 5 Blackwing only has one set of cats. No secondary.

removing the cats does not trigger a code
