With GPP's distinctive style and design, the Greddy Performance Products DD-R is their modern interpretation of the iconic GReddy DD “Dynamic Dual” exhaust of the past. GPP's distinctive DD exhausts with twin high-flow, low restriction compact muffler section, have always been recognized for its aggressive dual exit look and racey sound. With this new high-quality, race-inspired DD-R, Greddy also incorporated updated and improved, full 304 stainless-steel construction and new configurable features.

The DD-R compact dual muffler exhaust for the Honda (FC3) Civic Si coupe is designed for owners who desire a high quality, free-flowing exhaust with aggressive looks and sound to match.This full stainless-steel cat-back system begins after the front over-pipe with a 76mm (3”) front-pipe with tucked resonator to a full 3” mid-pipe all the way back to the rear section. The 3” piping then splits to two large 63.5mm (2.5”) inlets for the polished, 101.5mm (4”) DD-R mufflers via our precision Y-pipe. The DD-R is finished off with removable dual GPP engraved stainless steel slash-cut tips. The DD-R’s removable tips allow for customization with various optional tips and muffler silencers (sold separately.).
