Description

ESR SM Exhaust with Resonator MufflerThis exhaust still remains the best exhaust available for Spec Miatas. It routinely produces more HP and Torque than all of its competitors. This exhaust was original developed by Sam Henry of Springfield Dyno. Since taking over the line exclusively, we at ESR have addressed the fitment issue and now the exhausts fit perfectly without touching anything. We also changed the hangers to bullet tips so they are retained much better by the exhaust hangers.

They have no equal. Now available only at East Street Racing.

Available for 1.6, NA 1.8 and 99 plus cars

This exhaust comes split in half, we recommend welding it together. You can clamp it together, however we do not provide a clamp and advise against anything but welding together.

      Outstanding quality
      Size: 11, Color: Black Faux Leather, Size: 11, Color: Black Faux Leather
      The loafers are very comfortable with the puffy insole, very nice quality, and overall a very good shoe. I suggest a half a size up because they are kinda narrow.

      Size: 10, Color: Brown Faux Suede
      comfortable and nice-looking loafer. i wear 10.5 and ordered 10 and they fit fine. haven't worn them much yet so i can't say how they'll hold up but seem pretty nice for the price.
