    Expected ETA late Feb./ early March

    The Supreme SP for the 9th generation, (FB) Civic Si features our signature GReddy layout, styling and sound, with new revised piping diameter. It is designed to be compatible with both Si models; coupe and sedan (using the optional 11050108 adapter.) The straight-through resonator and specially-made oval muffler with off-set extended tip allows the system to follow the Civics’ bodies lines and help reduce drone and high pitch frequencies. It also provides good power gains throughout the usable power band. Like all GReddy Supreme SP systems the fully hand-welded 304 Stainless-Steel exhaust carries a Limited Lifetime Warranty.
