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: Because the Supreme SP for this model uses a factory type "donut gasket" flange to the factory piping, it fits both the 2013-16 FR-S / BRZ and the 2017-on "kouki" 86 / BRZ models (the slight change in the OEM factory over-pipe does not affect fitment on the Supreme SP).
