Same thing happened to mine on the way to the shootout in 2014. I determined it was where the EGR hookup was capped off and finally became stressed and blew apart.
Perhaps you recall Vining and I using Beer Cans to patch things up . Bud Light Ritas are about a perfect fit!

Still rocking the beer can repair? Lol I used a 1 7/8 coupler split in half perfect radius to go over the pipe and tigged it on
Very happy for you buddy
Really enjoying this thing!
I took it to the local muffler shop and had them weld some steel over the hole in a similar way as yours.
Like the new tags also!
