Description
The Flowmaster Flow FX Cat-Back Dual Exit Exhaust System is engineered for 2021–2026 Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon, and GMC Yukon XL models equipped with the 5.3L V8 engine. Designed to enhance both performance and sound, this system delivers a refined yet aggressive exhaust tone while maintaining everyday drivability and comfort.
The Flow FX system is tuned to bring out the deep V8 character of the 5.3L engine, delivering a confident cold start sound and a bold, controlled exhaust note under acceleration. During normal cruising, the system is engineered to minimize and eliminate unwanted cabin drone, ensuring a quiet and comfortable interior experience for daily driving, long trips, and towing. This balance makes it ideal for family SUVs that demand performance without sacrificing refinement.
Constructed from high-quality stainless steel, the Flow FX cat-back system is built for long-lasting durability and resistance to corrosion. It is designed as a direct bolt-on replacement using factory mounting points, allowing for a straightforward installation without cutting or welding. The dual rear exit configuration enhances the vehicle’s rear-end appearance, adding a more aggressive and premium factory-plus styling.
The system is optimized to improve exhaust flow, with performance gains of up to 12 horsepower and 11 lb-ft of torque at the wheels under ideal conditions. Premium black chrome quad exhaust tips complete the look, giving the vehicle a modern and performance-oriented finish.
Backed by the Flowmaster Limited Lifetime Warranty, this exhaust system is built to deliver reliable performance, enhanced sound, and long-term durability.
