95 Camry flex pipe dimensions

[stratovani]

I have a 1995 Camry LE with the 2.2L 4 cyl engine. Recently the car has been giving out a funny exhaust smell, and upon looking under the car I can see that the flex pipe is starting to shred and probably has a crack in it, so it needs to be replaced. The various auto parts stores have a variety of sizes and lengths in flex pipes, so I can't really tell what size pipe I'll need to get. Can anyone tell me what length and diameter flex pipe I should get?
