Supreme SP Cat Back Exhaust by Greddy
A large horizontally mounted, 3-section muffler with a “tucked-away” layout. 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.
