Interesting it looks like they've changed the catted xpipe design a bit since I bought my catted unit in 2018. I dunno, been a while. I need to check it out and see if mine are marked next time I'm down there, but I did confirm back then that they were using a 300cell
Never thrown a cat efficiency code, don't have a delete tune, so it's worked out great for me.
