Ideal for bolt-on turbo or supercharger kits or high-flow N/A applications, this version features large diameter 76mm (3") muffler and piping, with only a short inlet portion of 63.5mm (2.5") to allow it to still bolt up to factory catalytic converter flanges. The large mid-pipe resonator and off-set oval Supreme SP muffler allow for deep rich exhaust note throughout the B18 engine's RPM range. Careful attention to routing allows for simple install, and OEM like fitment. All GReddy Supreme SP systems the fully hand-welded 304 Stainless-Steel exhaust carries a Limited Lifetime Warranty
