No, they don't. I worked my way around it by getting a cat-back that fits 07-08 trucks instead of the 09+ connection. I didn't want to leave it up to someone else.

But, I saw this picture posted in another thread about Kooks and the 6.2... It clearly shows a different Y-pipe although no site ever mentions it. You might try PM'ing John Deere Racer, it was his thread they were posted in and he has a 2010 6.2

Looks like the ARH, great companies indeed. Congrats! Throw some installed pictures later on

Can't speak for the Kooks, but my ARH cats set cat efficiency codes for both banks after a couple of "trips" - P0420 and P0430.

Hmm, I think I like the Y on the Kooks better than the ARH. That's the first time I've seen a pic of the Kooks Y posted.
