i have a 97 cavalier sedan, and a 04 eco are the mufflers and the bends the same from the muffler foward for like maybe a foot or so?

Just asking, but if you have both cars why not just look?

they are the same. any aftermarket exhaust from 95-05 will fit so theres your answer. the dash barely even changed, do really think anything else would

The factory cat-back parts are the same on just about all J-bodies.

The early 2.2L's *might* be different, I'm not sure since it's been years since I looked at one.... but I know there's a slight difference between headers for the 95-97 2.2L and the 98-02 2200. I'm almost certain the cat-back portion is identical for all the cars though.

The tips are a bit different... dual tips on the 95-early 02 Z24's, dual exhaust on the Sunfire GT's, chrome tips on the late 02-05 LS Sport/Z24 in Canada. Minor differences though.
