Wouldn't hurt a thing. In fact the engine will probably breathe considerably better since the almost 20 year old cats are sure to have some junk in them!

Removed the cat from my '90 about 9 months ago and it made a noticeable difference. No codes or side effects as of yet.

What difference did it make? run better, better mpg or just louder?

If you decide to gut the cat, just remember that crap inside is toxic as hell. Gloves and a mask of some sort or better yet a respirator.
