Anybody know the factory exhaust diameter for 1999 Tahoe?

2" down pipes and maybe 2 1/2" tailpipe. I have a complete one off if need actual dimensions.

My 99 4 door was 2" OD to the muffler, 2.75" tail pipe.

My 99 4 door was 2" OD to the muffler, 2.75" tail pipe.

Same with my 2-door.

Same with my 2-door.

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.

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.

Thanks guys, I want to make sure cause I want to get a Flowmaster muffler exhaust, and a polished muffler tip so I want to make sure I get the right parts, hey b454rat can you please measure the size at the muffler inlet, and exit tip?

Thanks in advance..

Mine was 2-in and 1-out. I say "was" because it is no longer stock. I now have a 2-in and 2-out Magnaflow with dual tips.

Mine is 100% stock exhaust.

The 2 pipes that go into the muffler? They are about 2". But can get a pic with measurements if needed.
