My 99 4 door was 2" OD to the muffler, 2.75" tail pipe.
I have seen some with a Y-pipe and a single pipe to the muffler. GM changed some SUVs and Vans to a Y-Pipe some where in 99.Same with my 2-door.

For reference the 8-lug trucks were 2.75" dual to the muffler and a 2.75" tail. My 97 van was dual 3" to the muffler and a 2.75" tail. Dual 3 to single 4 now.
