Greddy introduces their Supreme SP catback exhaust system for the Subaru WRX and STI. The Supreme SP for the (VA) Subaru Sedan features large dual oval mufflers and quad staggered tips in a "tucked-away" layout, for maximum muffler ground clearance. Large 76mm (3”) piping is carefully routed around the rear differential to a centralized Y-section for more even flow. This creates and improved performance with exceptional sound for both the EJ powered STI and FA powered WRX applications. The system is finished off with classic quad Supreme SP 89mm laser engraved GReddy tips. Like all GReddy Supreme SP systems, the fully hand-welded 304 Stainless-Steel exhaust carries a Limited Lifetime Warranty.
