I considered it when I was installing the Dynamax.  I was advised not
to use it by the installer (who also builds and installs his own
performance exhausts and races his own cars) because the lack of back
pressure would cause a noticable reduction in torque.  The Miata can't
afford that, so I stuck with the Dyna.
