The Supreme SP for the Subaru STI Sedan features much larger diameter piping, resonators and mufflers, but also smoothes the layout for maximum performance with good sound suppression. This cat-back exhaust starts out with a full 3” mid-pipe with a large straight-through resonator to tune out drone. The next section smoothly transitions into dual 2.5” diameter piping. Improved dual GReddy straight-through mufflers with dual, double wall tips on each muffler finish off the exhaust. GReddy designers carefully position the dual mufflers and staged tips to flow with the GV-chassis’ bodylines. Like all GReddy Supreme SP systems the fully hand-welded 304 Stainless-Steel exhaust carries a Limited Lifetime Warranty.
The Supreme SP for the Subaru STI hatchback features a large horizontally mounted, 3-section muffler with a center inlet. This routing allows for the large 3” diameter piping to more smoothly enter the muffler’s center section. Exhaust gases exit each side of the revised muffler via the two 2.5” diameter piping to quad staggered 3.5” GReddy double-wall slash cut tips, The non-tapered 3” mid-pipe also encases a large resonator section to tune-out drone. Like all GReddy Supreme SP systems the fully hand-welded 304 Stainless-Steel exhaust carries a Limited Lifetime Warranty.
