What company did you go with on your long tube headers

I have a 2017 silverado 1500 LT Crew Cab. I will be installing long tube headers and need to know what size diameter is the y pipe connector to the male ball socket diameter that connects to the expansion pipe in front of the muffler? My kit did not come with this.

What size male ball goes into the female socket on the 5.3l? The long tube headers kit I got doesn't have the connector pipe from the long tube headers to this expansion pipe.

What is the diameter size of that socket for the 5.3l?
