The Supreme SP for the 4th generation ND Mazda Miata was designed and engineered specifically to suit the USA spec 2.0l Skyactiv-G engine combination.  Unique to this application is the availability of either the pre-resonated axle-back muffler system, for maximum sound control with enhanced flow.  Or there is also a full system, that includes a dual resonated mid-pipe for even more performance and a sportier sound.  The full system showed power increase throughout the RPM band, with maximum gains, of 13hp/8ft-lbs, as low as 3500rpm.  Both options use the same unique rear section with dual 82mm GReddy exhaust tips.  Like all GReddy Supreme SP systems the fully hand-welded 304 Stainless-Steel exhaust carries a Limited Lifetime Warranty

The Mazda Miata Supreme SP exhaust will arrive by the end of Dec...
