GReddy Supreme SP Cat-Back Exhaust Subaru 2008-2014 STI Hatchback

The Supreme SP for the Subaru STI hatchback features a large horizontally mounted, 3-section muffler with a "tucked-away" layout. This routing allows for the large 3 inch diameter piping to more smoothly enter the mufflers center section. Exhaust gases exit each side of the revised muffler via the two 2.5 inch diameter piping to quad staggered 3.5 GReddy double-wall slash cut tips, The non-tapered 3 inch 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.
