Crafted for the 10th gen Honda Civic Si coupe, the GReddy Supreme SP dual muffler system delivers performance and sound excellence. This full 3-piece cat-back exhaust begins with a 3-inch (76mm) front and mid-pipe, designed to fit right onto the factory downpipe. It transitions into two lustrous SP oval mufflers, ending in dual center-exit tips that accentuate the Civic Si's athletic stance. Optimized for the turbocharged 1.5L engine, it provides an unmistakable GReddy growl under hard acceleration, while the premium hand-welded 304 stainless steel construction promises durability and comes with a Limited Lifetime Warranty.
