I read the other thread and I would say to put that new catalytic converter on if you havn't already. Which type did you get? You shouldn't have to weld it on. I replaced mine with a Dynomax high flow and it passed with flying colors. Everything was WAY under the limit. I'll try and find the printout they gave me for the exact numbers.
