Flex pipe size?

I have a 1994 SL2, automatic...does anyone know what size flex pipe I need to get to match existing?

IIRC its 2.5''

Okay, thanks...how about length? I will crawl under the car this weekend to see, but might as well ask anyway. Or does it depend on how far it is cut off?

Not sure on the length. Best bet is to just measure it :)
