Capristo's sport cat downpipes are engineered for the Audi S8 (D4) and S6/S7 (4G) platforms, offering a significant upgrade in exhaust performance. These components feature high-flow 250-cell sport catalytic converters designed to reduce backpressure and enhance exhaust gas velocity, contributing to improved engine responsiveness and power output. Constructed from premium T309 (1.4828) stainless steel, these downpipes are built for longevity and resistance to corrosion. Each unit is meticulously manually TIG welded by skilled craftsmen, ensuring robust and precise construction. This product serves as a direct replacement for OEM part numbers 4G0254202NX and 4G0254252LX. The downpipes are specifically designed for the Audi S8 (D4) models from 2012-2018, including the S8 Plus, and for the S6/S7 (4G) models from 2012-2018. Installation is recommended for off-road use or in regions where emissions regulations permit.
