Where is the cat on an s13?

I've got a 93 240sx s13 coupe, 5 speed.Where is the cattlytic converter(s)?I've read some posts saying that it's on the manifold, but they did not say it pertains to an s13 or not. It looks like it's under the driver seat under the floor pan. Is that a resinater or a catty? Is it truly on the manifold? It doesn't look like it's on the manifold, but I just want to get it cleared up.

Another thing I can't figure out is if I have an LSD or open diff. If I spin one back tire the other one moves a little, but it's not as fast as the one i'm spinning. This happens on both sides. Is there a way to know using the VIN # or something? A serial # on the diff.?

It's not in the manifold, the manifold bolts to the cat. It's right under the driver's seat. With a VLSD, if you spin one the other spins the same way. Open diff, spin one, the other spins the opposite way.

Altamonte Springs. close to state road 434 and 436. Why?Turns out it's an open diff.

you can also look for an orange sticker that would be on the diff if you have vlsd, if not, it's not there
