GReddy 17-21 Honda Civic SI Sedan Supreme SP Exhaust (10158217)
Our dual muffler Supreme SP cat-back exhaust is tailored to the 10th generation (FC1) Sedan model of the Honda Civic Si. The extended sedan version has similar features to our coupe counterpart, including high flow with a tuned exhaust note. The system produces the distinctive GReddy deep exhaust grumble while driving aggressively at wide-open throttle. This three-piece, cat-back exhaust expands to a large 3" (76mm) forward-mid pipe and mid pipe that split to two polished, straight-through SP oval mufflers and dual center-exit dual-wall GReddy tips to improve the performance of the turbocharged 1.5L engine. Our system bolts to the factory exhaust system at the flange behind the engine/transmission. The sedan version has a slightly more aggressive tip angle and the muffler combination is a better compliment to the Si sedan’s sporty, but wide rear bumper tip opening. Like all GReddy Supreme SP systems, the fully hand-welded 304 Stainless-Steel exhausts carry a Limited Lifetime Warranty.
