Flowmaster 5.3L F&R Cat-Back Exhaust For GM Silverado/Sierra 1500 (14-26) (717894)

The Flowmaster FlowFX Cat-back exhaust system is a high-performance upgrade designed for 2019–2026 GM Silverado and Sierra 1500 trucks with a 5.3L engine and factory dual exhaust. Constructed entirely from durable 409 stainless steel, this bolt-on system features a 3.00-inch inlet pipe that connects to a single inlet/dual outlet FlowFX straight-through muffler, delivering a deep, moderately aggressive sound. It maximizes performance with dyno gains of up to 21 horsepower and 26 lb-ft of torque at the rear wheels. The dual 2.50-inch mandrel bent tailpipes are carefully routed to clear factory components such as the spare tire and tow hitch, exiting through the factory exhaust bezels in the bumper to maintain the original dual exhaust appearance. The system utilizes factory hanger locations, includes installation instructions, and all necessary hardware for straightforward at-home installation.

This exhaust system is compatible with both 2WD and 4WD models of the specified trucks, serving as a direct bolt-on replacement for the factory setup. It is ideal for street-driven trucks seeking improved sound and performance without sacrificing factory appearance. Designed for ease of installation, the kit includes all components needed for a hassle-free upgrade, making it suitable for daily driving, towing, or performance enhancement. The system enhances exhaust flow and sound profile while maintaining factory fitment and clearance, ensuring a seamless upgrade for Silverado and Sierra owners.
