catback exhaust for 08 wrx

ok my question it that i know a lot of Subaru parts are able to swap out with other years now i have an 08 wrx and the root of the question is can an 07 catback work for my 08 and would an 08 wrx wagon work on an 08 sedan thanks for the help and sorry to sound so dumb

 

I think it should work, but I'm not entirely sure, as I drive an Evo X, so I'm not really all that qualified.

 

i know that 07 and earlier were all basically the same underneath...but in 08 they made serious changes. if i'm not mistaken, 2008 they switched to the dual exhaust...right?
