The Flowmaster Flow FX® Cat-Back Exhaust System is engineered to deliver improved performance, durability, and a deep, moderate exhaust tone for 2019-2026 GM 1500 trucks equipped with the 2.7-liter turbocharged engine. Designed for maximum exhaust flow and long-term reliability, this system is constructed entirely from high-quality 16-gauge 409 stainless steel.

This performance cat-back exhaust features a single 3.50-inch inlet that transitions into dual 2.50-inch mandrel-bent pipes, ensuring smooth exhaust flow and reduced backpressure. At the core of the system is Flowmaster’s Flow FX straight-through performance muffler, delivering a refined yet aggressive tone while maintaining comfortable interior sound levels.

Dyno testing shows gains of up to 9 horsepower and 12 lb-ft of torque at the rear wheels, making this system an ideal upgrade for both daily driving and performance applications. The dual side exit design exits behind the rear wheels and is finished with dual 4.50-inch black ceramic-coated exhaust tips, providing a bold custom appearance.

This bolt-on system utilizes factory hanger locations and includes all necessary hardware and detailed installation instructions for an easy at-home installation. Backed by Flowmaster’s Lifetime Limited Warranty, this exhaust system delivers proven performance and lasting value.
