The Supreme SP for ever-popular (FG) Civic Si coupe embraces the classic GReddy Civic styling that has made the SP line so popular over the years. Stand out features of this latest version include: larger diameter 63.5mm (2.5”) piping, updated resonator, improved muffler section, and our new Limited Lifetime Warranty.. Like all GReddy exhausts, it’s the ideal combination of fitment, styling, performance and deep exhaust note, that sets it apart from the competitors. It is also designed to be compatible with both Si models; coupe and sedan (using the optional 11050104 adapter.) Each GReddy Supreme SP system is a fully hand-welded 304 Stainless-steel exhaust.
