Is there a difference between the size of exhaust in a 2.0L wrx sti 2004 impreza and the 2.5L hawkeye?

 

i would have to say there is, as when looking for a new exhaust for my blob theres a seprate selection for hawkeye

 

Overall it is the same size but i think it joins in different areas, So could become a pain to mix and match, I think the backbox and centre section are the same but its different from the turbo to 2nd decat(Different lengths)
