What is the inlet and outlet size for the 5.3's muffler, I got a 3 inch in/out muffler, and the inlet seems to fit fine, but the outlet is too small
What can I do to make the outlet fit, what exhaust reducer will I need

It did weld up, but theirs gaps all the way around that were filled in with welds
I'm kind of worried about it so I was hoping to find a reducer...

It looks good, but I still would prefer a reducer
so is their a 3 to 2.75 reducer?
