You might be better off searching through Miata.net because there will be more Miata owners there. Everyone will have different preferences on what makes a good exhaust system. I for one like something more race inspired so I chose the RS*R GTII exhaust. Which I know for a fact some people would not like because of the noise and looks. Then there are those who want functionality and don't care about look and I assume those people would go for the Enthuza exhaust. Either way I hope you find the info you're looking for.
