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 Scion FR-S & Subaru BRZ features a large horizontally mounted, 3-section muffler with a center inlet and an unique, tuned, internal “Y-pipe.” This directs exhaust gases through a center chamber to reduce overall sound and improves flow to the outer straight-through sections. These outer sections of the muffler have our updated high-temp, internal sound suppression system. The exhaust is finished-off with dual GReddy slant-cut, double-walled tips in the factory bumper outlets. This cat-back exhaust also uses a simplified exhaust pipe routing with a large straight-through resonator in the mid-pipe, to tune-out any drone. Like all GReddy Supreme SP systems the fully hand-welded 304 Stainless-Steel exhaust carries a Limited Lifetime Warranty.

NOTE:  Becuse the Supreme SP for this model uses a factory type “donut gasket” flange to the factory piping, it fits both the 2012-16 FR-S / BRZ and the 2017-on “kouki” 86 / BRZ models (the slight change in the OEM factory over-pipe does not effect fitment on the Supreme SP).
