Description

The Performance-Curve dual exhaust kit is a mandrel-bent system engineered for 1996-1999 Chevrolet and GMC trucks featuring the 5.7L engine. It includes dual 2.5-inch OD inlets and dual 2.5-inch outlets, integrating an X-pipe configuration. The X-pipe design promotes better scavenging and a more aggressive exhaust note. Constructed for durability, this kit is built to withstand the demands of daily driving and performance use. Installation is intended to be a direct fit replacement for the factory exhaust system, though professional installation is always recommended for optimal results and safety.
