The DynoMax kit for the 4.0 Mustang, 05-10 is part number 39434. It comes with an X pipe, both mid pipes, mufflers, clamps and hangers. I have this kit basically. I bought the parts out of it except for the mufflers (I used GT takeoffs) and the right mid pipe (same as the v6 pipe-just reuse the old pipe.). You can order the individual parts out of the kit, and get just what you need. Much cheaper way to do it, and you don't have parts lying around rusting away. You can look up the numbers at the DynoMax site. Hope this helps.
