Description
Upgrade the sound, performance, and appearance of your full-size truck with the Flowmaster Force II Cat-Back Exhaust System, engineered specifically for 2011–2018 Chevrolet Silverado and GMC Sierra 1500 trucks equipped with the 6.2L engine. This system delivers noticeable performance gains while maintaining a moderate interior and exterior sound level, making it ideal for daily driving and towing applications.
Constructed from durable stainless steel, the Force II system features large 3.50-inch mandrel-bent tubing that improves exhaust flow and efficiency. Exhaust gases are routed through a Flowmaster 50 Series Big Block chambered muffler, producing a muscular exterior exhaust note while the integrated Helmholtz chamber helps control unwanted interior resonance.
Designed as a direct bolt-on system, this cat-back exhaust uses factory hanger locations for a clean, hassle-free installation. The system exits with a single side exit and is finished with a highly polished 4.00-inch 304 stainless steel exhaust tip, embossed with the Flowmaster logo for a premium appearance.
Each system is dyno tuned for maximum performance, built to Flowmaster’s high-quality standards, and backed by a Lifetime Limited Warranty for long-term confidence.
