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 for the Mazda RX8 features dual horizontally-mounted straight through mufflers connected by a smooth center “Y.” The larger 2.5” piping routing provides smooth flow. Dual wall Supreme SP tips fit nicely through the factory rear bumper exits. It’s a great sounding exhaust for a stylish 2004-08 RX8 cat-back. Like all GReddy Supreme SP systems the fully hand-welded 304 Stainless-Steel exhaust carries a Limited Lifetime Warranty.
