Flowmaster FlowFX Cat-Back Exhaust System - Compatible With 2019-2024 Chevy Silverado/GMC Sierra 5.3L

This Flowmaster FlowFX cat-back system will completely transform your truck's sound and performance. Designed specifically for 2019-2024 Chevy Silverado and GMC Sierra 1500 crew cab/double cab models with the 5.3L engine, it delivers a deep, powerful tone that sounds amazing without being obnoxiously loud. The system features 3-inch tubing that reduces to 2.5-inch, all mandrel-bent from durable 409 stainless steel. You'll get noticeable performance gains too - up to 21 horsepower and 26 lb-ft of torque according to dyno tests. The straight-through FlowFX mufflers provide great flow while the dual rear exits use your factory exhaust bezels for a clean, OEM-plus look. Installation is straightforward if you're handy with tools, and the quality is exactly what you'd expect from Flowmaster.
