Overview
Supreme SP Exhaust for 2017+ Civic Si Sedan by GReddy
The Supreme SP cat-back exhaust, for the turbocharged 10th generation Honda Civic Si Sedan, improves the performance, sound quality and styling, by applying our signature SP (Street Performance) ideals into the design.
The system not only incorporates large 76mm (3”) piping, but smoothest out and simplifies the heavier, factory muffler layout with the free flowing, compact oval SP mufflers. This allows the engine to be more efficient for added performance, without having drone or being loud. The Supreme SP sound level was carefully tuned not to require any additional resonators; this also helps lighten up the system.
The polished stainless-steel center-exit exhaust is finished off with stylish dual, double-wall, slant cut GReddy tips, to enhance the Civic Si's sporty rear diffuser. Like all GReddy Supreme SP systems, the fully hand-welded 304 Stainless-Steel exhausts carry a Limited Lifetime Warranty
