This Flow FX 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" Flow FX performance muffler delivers a moderate yet deep and powerful sound while the interior sound is kept very mild. The system uses the factory hanger locations and is finished off with two 4.50-inch black ceramic-coated 304 stainless steel tips embossed with the Flowmaster name exiting on each side of the truck. The kit includes detailed instructions and all hardware necessary for a quick and easy installation you can do at home. Backed by Flowmaster's Lifetime Limited Warranty.
