Exhaust question!?

I currently own a 2006 wrx, completely stock exhaust system with an axleback. 

My friend is offering me his catback that was made through an exhaust shop. He owns a 2003wrx. Are these interchangeable? Mine has the cats in the downpipe, where his were in the catback. If I pull his cat off his catback then realistically it should fit. I’m just not entirely sure if I’ll have to modify it? Or it should fit..

    Look up the parts numbers for both car's exhaust systems on an auto repair store web site and see if they match. If they dothe exhausts are interchangeable.
