Some folks modify their Miatas for aesthetics.
Others will do anything to eke a slight performance improvement out of the engine. Once in a while, a product will come along that satisfies both camps. One of these is the Flyin' Miata Dual exhaust. It's hard to ignore the visual aspect of dual 89 mm tips sticking out from under a Miata's rear bumper. Those tips are chromed as well, just to make sure they're noticed.
