Dual exhaust? I don't think that'll be efficient or necessary. A bigger cat-back exhaust with thicker piping would help.
And if you want to mess with boost (and even if you don't), get a boost guage.
Have you tried looking in miata forums for info? Not knocking our awesome site, but I think MSM owners might be more plentiful in a miata site, and they'll know more about aftermarket parts being made for the MSM.
