Description
Take your 2024–2025 Chevrolet Silverado or GMC Sierra 1500 6.2L to the next level with the Flowmaster® FlowFX® Cat-Back Exhaust System. Designed to deliver aggressive sound, reliable performance, and durable construction, this high-flow system adds serious character to your truck. Built from robust 409 stainless steel with mandrel-bent tubing, the FlowFX system improves exhaust flow and is made to last through harsh conditions.
This cat-back setup includes a specially tuned FlowFX straight-through muffler that produces a deep, moderate-to-aggressive exhaust note while eliminating interior drone. Dual 2.5-inch tailpipes exit through the factory bumper cutouts and retain the OEM bezel for a clean, factory-style finish.
Equipped with active valve technology and integrated turndown, you can control exhaust volume directly from your truck's drive mode selector. Run quiet in Normal mode or unleash full sound potential in Sport or Off-Road mode. Peak dyno results show gains of up to 15 horsepower and 13 lb-ft of torque at the wheels—performance you can feel on or off the road.
This system is a true bolt-on upgrade, using factory hanger locations and clamp-on installation. All required hardware and instructions are included, and the system is backed by Flowmaster’s Lifetime Limited Warranty.
