97 To 99 V6 Mustang Y Pipe Interchangeable? Suppp

[Bradley t]

I have this posted on another forum as well but so far no response... I'm looking at picking up a 97 v6 from a friend that has good cats and I want to see if I can take the y pipe off and put on my 99 v6 that won't pass CA smog... does anyone know if it is compatible... supposed to pick it up this morning so trying to get quick response thanks
