This Flow FX cat-back exhaust system is designed for the 1987-1993 Ford Mustang GT with the 5.0L engine. Features include 409 stainless steel construction for added durability and 16-gauge 2.5-inch mandrel-bent tubing for unrestricted exhaust flow with tailpipes that exit in the stock location behind the rear valance. The stainless "straight-through" Flow FX performance mufflers deliver a moderate yet deep and powerful sound while the interior sound is kept very mild. The system uses the factory hanger locations and 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.
