exhaust interchangeable between 5.2 and 4.0?

i bought my 5.2 with the exhaust cut at the midpipe so no cat, no o2's, no muffler. junkyards dont sell cats and hack the exhaust up so i am looking online to see who is parting out their zj and all i can find are people with 4.0 so im wondering will this work for my engine and can i pass emissions with it? is the cat the same size? the muffler?

thanks in advance guys.

Check rockauto.com
If I remember correctly the Y pipe. Cat. Muffler. Tailpipe all of it was $250.

Are u missing the front O2 also or just the second one after the Cat.
