Your car has equal length headers, 2007 onwards GT had the unequal headers.
To change your headers you would also need to change your turbo I think, because of it being a twin scroll setup. So headers + Turbo + dump pipe to get the "boxer rumble".

Although I am able to achieve the boxer note with just a cat back quite nicely. I can only imagine the note will improve again with a dump pipe. Oh and yes, I do have an 07 face lift model.
