Not sure what 12599 is, maybe they replaced the design with a true x design or it’s a new part itself.
However 12469 still exists for sale from numerous places.
Actually I just double checked. 12599 is a completely different part #/muffler.

I have the 12469 muffler and its a true X internally. I'm thinking there were earlier versions that may not have been a true X muffler and had a single 3" section but later revisions were true X internally. I wouldn't have installed it on mine if it was a single 3" pipe internally, I visually looked through mine and it was a true X internally. Its possible if they have the same PN that some retailers might still have the older version in their warehouse and some might still be receiving those when ordering. I'm half tempted to order one from Amazon just to take some internal pics and then return it to put this issue to bed.
