Lets talk Catalytic Converter positions

On my 94 Suburban 2500 7.4, 2wd, my cat is AFTER the muffler just before rear axle. It looks fairly new, but my smog test, I just squeaked by by points of failing on 1 part(i will have to look which one).
I thought a cat needed to get HOT to be efficient? If I put in closer to the front, where does it go?
Thanks
