?? i cannot get a socket or a wrench on the nut at all. wondering if there is a special tool maybe

I am installing new catalytic converters on my 2001 ls. Came to a stop when i reached the nuts that hold the exhaust to the manifold. One nut comes off very easily, while the other seems impossible. Am i missing something?? Specialty tools required??
