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.

GReddy Supreme SP – HG (High Grade) is our premium stainless-steel cat-back exhaust for the (FK8) Civic Type R. Besides the looks of the HG’s fully polished stainless-steel mandrel-bent piping and unique, functional GReddy three tip configuration; extensive research and development has lead to this supreme exhaust system. Careful attention was placed on the Civic Type-R’s exhaust sound characteristics, when incorporating our purposeful, high-flow, tri-routing layout. The large 76mm (3”) diameter piping flows smoothly through a large mid-pipe resonator and then branches out to the high-flow 3” center SP muffler and the two side-mounted sound chambers, before exiting the GReddy triple exhaust tips. Like all GReddy Supreme SP systems, the fully hand-welded 304 Stainless-Steel exhausts carry a Limited Lifetime Warranty.
