Exhaust Help

First post, first time foxbody owner. Just picked up an 89 notchback with a 2.3 and the exhaust needs to be replaced. Im looking on rock auto and they have walker exhaust and the catalytic converters are listed as front and rear. Did these cars come equipped with 2 cats or are there two different style exhaust systems. I am currently not with the car at the moment or I would get my butt under the car and look.

Does the 2.3 have to cats?

Does anybody know the answer to this question? means village doesn't 89 Mustang have 2 catalytic converter's

Thanks for the response and sorry I'm using voice command on my iPhone that's why my writing is not making sense..to=two. I looked under the car and I only see one catalytic converter towards the rear of the main pipe coming out of the exhaust manifold, closest to the intermediate pipe. The entire exhaust is just rusted not worth patching up. Before I order from Rockauto I just want to make sure I'm ordering the right stuff. Not sure why they are listing a front catalytic converter and a rear catalytic converter but that is confusing me. To convertibles have a different set up. I'm kind of shocked at the lack of support on this because the Ford Mustang is an extremely popular car. I could see if I was restoring a 72 Peugot...
