This FlowFX cat-back exhaust system is designed for the 1996-1999 Chevrolet/GMC 1500 Extended Cab/Short Bed trucks with the 5.7L engine and dual catalytic converters. Features include 409 stainless steel construction for added durability and 16-gauge 3.0-inch to 2.5-inch mandrel-bent tubing for free unrestricted flow. The compact oval "straight-through" FlowFX performance muffler delivers a moderate yet deep and powerful sound while the interior sound is kept very mild.
