ka24det wont pass emissions

[greenb0y]

Hey guys, new to the forum and have a question for everyone.
I recently purchased an s13 from jersey with a ka24det in it.
I live in PA currently and car needs inspection/emissions.
Passed inspection but can not pass emissions.
I was told to try and get a catalytic converter back on the exhaust.
Is it possible for my to cut, weld new flanges, and just simply stick the cat on my aftermarket exhaust?
Im running into trouble because of my downpipe coming from the turbo.
Let me know what you guys think and sorry if this is a noob question!

yes you can cut and weld one in place although i would get a shop to do so, as some places require the cat to be in a certain place under the car.
