GReddy's Supreme SP cat-back exhaust system is engineered specifically for the turbocharged 10th generation Honda Civic Sport hatchback, merging enhanced performance, auditory refinement, and aesthetic appeal. Drawing upon the principles of Street Performance (SP), the design features a large 3-inch (76mm) piping that replaces the stock dual-muffler setup with a streamlined, single-entry, dual-outlet, oval SP muffler. This optimization allows the L15 turbo engine to perform more efficiently, boosting performance without excessive noise. Meticulously tuned to eliminate the need for extra resonators, this system reduces weight while maintaining a pleasant sound profile. The polished stainless-steel, center-exit exhaust culminates in a pair of sleek, double-wall, slant-cut GReddy tips, accentuating the Civic's sporty rear profile. As with all GReddy Supreme SP systems, this cat-back benefits from a Limited Lifetime Warranty and is crafted from fully hand-welded 304 stainless steel.
