    Sound wise I agree with you. But the purpose of dual exhaust is not only for sound, but many times for performance (2x 2.5" pipes flow more than 1x 3" pipe). Performance wise, there is some performance gain possible from X or H-pipe (X being the recommended). The amount is arguable, but is based on how much back pressure exists in the 2nd half of your exhaust system. If you don't have high flowing cats/mufflers, placing an X in front of them will equalize the pressure in the back half of the exhaust system, providing a more even flow out of both sides of the system. The downside, as you mentioned, is that it sounds more even or uniform on both sides.

    Obviously the best is headers to open air, and I would deem the benefits of an X before high flow mufflers or glass packs to be negligible.
