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.
