GReddy 16-17 Mazda Miata (Manual Trans Only) Supreme SP Stainless Steel Cat-Back Exhaust

Within the muffler, new straight-through and directed- straight-though chambered muffler designs allow GReddy to engineer a more refine exhaust note while increasing exhaust flow and performance. Classic GReddy street performance styling is maintained with excellent fitment and a stylish exhaust system layout. The Supreme SP not only designed to perform and sound great for each specific application; it matches the vehicle’s body-lines and styling.  

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 cat-back 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.
