RoadsterSport 3 Muffler
The stock muffler sound of the NB Miata is right off a sedan. Not
appropriate for a sports car. This is one of the most popular
aftermarket exhaust systems. It is very difficult to shop for
one of this because you pretty much purchase them site unseen as far
the loudness goes. The RS3 is in the middle range of
loudness. I ran this with the baffle installed and still found
it a bit to loud and boomy when it got fully heat soaked.
