Flowmaster FlowFX 5.3L Cat-Back Exhaust For GM Silverado/Sierra 14-19 (717893)

The Flowmaster Flow FX Cat-Back Exhaust System is a high-performance exhaust upgrade designed for the 2019-2026 Chevrolet Silverado and GMC Sierra 1500 models with a 5.3-liter engine. Constructed entirely from durable 409 stainless steel, it features a 3.00-inch inlet pipe that connects to a single inlet/dual outlet Flow FX "straight-through" muffler, delivering an aggressive sound and maximizing horsepower and torque. The dual 2.50-inch mandrel-bent tailpipes exit at an angle behind the rear wheels, effectively directing exhaust away from trailers or boats when towing. Finished with large 4.50-inch black ceramic coated stainless steel tips, the system enhances both the visual appeal and sound profile of the vehicle. It uses all factory hanger locations and includes an additional hanger for the left side tailpipe, along with installation hardware and instructions for straightforward, DIY installation.

This exhaust system is compatible with both 2WD and 4WD versions of the specified trucks, serving as a direct bolt-on upgrade to improve sound, performance, and aesthetics. It is ideal for daily driving, towing, and performance enthusiasts seeking a deep, aggressive exhaust note and increased horsepower—up to 18 hp and 21 lb-ft torque on the rear wheels. The kit includes all necessary components for installation, making it suitable for at-home installation without modifications. Designed specifically for the 2019-2026 Chevrolet Silverado and GMC Sierra 1500 with the 5.3L engine, this system provides a durable, performance-oriented upgrade that enhances your truck’s sound and power.
