Upgrade the tone, flow, and overall performance of your truck with the Flowmaster Flow FX Cat-Back Exhaust System, designed for the 2009–2013 Chevrolet Silverado 1500 and GMC Sierra 1500 equipped with the 4.8L or 5.3L V8 engine. Built from durable 409S stainless steel, this system delivers long-lasting corrosion resistance and a deep, powerful exhaust note.

A 3.00-inch inlet pipe feeds into a straight-through Flow FX performance muffler to maximize exhaust flow, enhance throttle response, and create an aggressive to moderate sound both inside and outside the vehicle. The single 3.00-inch mandrel-bent tailpipe exits behind the passenger-side rear tire and is finished with a 4.50-inch black ceramic-coated 304 stainless steel tip for a bold, custom appearance.
