2006 2500 Flex pipe Size

Hello, does anyone know what the flex pipe diameter is for a 2006 Sprinter 2500? I went to my parts site of choice and they list 3 sizes I am looking for the peice of flex that is right near the transmission. Any insight is appreciated! Be well!

Can't you just measure the flex pipe on your Sprinter? It might be (doubt it though) specific.

I believe 2 and 3/8" is the size, but many shops will use 2.5" because it's more common. Do not quote me on this though, I can measure it sometime tomorrow if nobody else knows

Thank you!
