have no caty

[GrandNational87]

i have no cat and im wondering can i use one off of just a buick regal from the junkyard will those fit.. or is there another way i can pass without spending so much like ex. making my straight pipe look like a cat.. dont want to spend money on some stupid thing that i will pull of a sec later...

It would probably pass more easily with a cat in place. Especially if the emisions are close to passing.
