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.
