The legacy of the GReddy SP lives on with GReddy’s best version yet, the Supreme SP and to prove it carries a limited lifetime warranty! From the 1st flange to the new double-wall GReddy Tip, each Supreme SP system features a high-quality, hand Tig-weld 304 stainless-steel outer construction. 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 cat-back exhaust, for the turbocharged 10th generation Honda Civic Sport hatchback, improves the performance, sound quality and styling, by applying our signature SP (Street Performance) ideals into the design. The system not only incorporates large 76mm (3”) piping, but smoothes out and simplifies the heavier, factory, two muffler layout with a free flowing, compact single entry, dual outlet, oval SP muffler. This allows the turbocharged L15 engine to be more efficient for added performance, without having drone or being loud. The Supreme SP sound level was carefully tuned not to require any additional resonators; this also helps lighten up the system. The polished stainless-steel center-exit exhaust is finished off with stylish dual, double-wall, slant cut GReddy tips, to enhance the Civic’s sporty rear diffuser. Like all GReddy Supreme SP systems, the fully hand-welded 304 Stainless-Steel exhausts carry a Limited Lifetime Warranty
