Upgrade your 2019–2023 GM Silverado or Sierra 1500 with the Flowmaster® Flow FX® Cat-Back Exhaust System, engineered specifically for trucks equipped with the 6.2-liter V8 and factory dual exhaust. Built from 3.5-inch to dual 2.50-inch mandrel-bent 16-gauge 409 stainless steel tubing, this system boosts exhaust flow, improves durability, and delivers a deep, moderate Flow FX performance tone.

A Flow FX straight-through muffler ensures maximum efficiency, while dyno testing shows impressive gains of +26 horsepower and +39 lb-ft of torque at the rear wheels. Designed to retain a clean factory appearance, the system connects directly to the OEM rear bumper-exit dual exhaust tips for a stealthy upgraded look.

Installation is straightforward thanks to the use of all factory hanger locations, and the kit includes hardware and instructions for an easy at-home setup. Backed by Flowmaster’s Lifetime Limited Warranty.
