Description
Overview
The Flowmaster Chevrolet, GMC (6.2) Exhaust System Kit is an American Thunder cat-back exhaust system engineered to transform the sound and attitude of the 2024 to 2026 GM 1500 trucks equipped with the 6.2-liter engine. Whether you drive a Silverado or a Sierra, this performance exhaust lets you personalize your truck with an aggressive-yet-moderate tone and a purposeful appearance that stands apart from the factory setup.
Built from 409 stainless steel, this exhaust system is designed for years of trouble-free service. It flows through a 3.50-inch inlet pipe into a specialty-tuned 50 Series HD style muffler, delivering the deep, muscular sound Flowmaster is known for while helping the 6.2 breathe more freely. Max dyno gains of 15 hp and 13 lb-ft at the rear wheels give you power you can genuinely feel behind the wheel.
Sound Control You Command
This catback exhaust integrates active valve control with an integrated turndown, allowing you to command the factory valve directly from the dash using your truck’s drive modes. Run the valve closed in Normal mode for a more civilized drive, then open it up in Sport or Off-Road mode for maximum sound. Because the system reuses the OEM valve actuator, you keep full, factory-style control over your exhaust note.
Design & Tips
Dual 2.5-inch mandrel-bent tailpipes exit through the factory bumper cut-out locations, capped with custom quad-exit 4.0-inch black ceramic tips for a bold performance look. The silver pipe and black muffler finish gives this exhaust system a clean, aggressive presence that complements the truck’s factory styling.

Fitment & Installation

There’s no need to cut or fabricate — the catback design mounts to the OEM hangers and exits through the bumper cut-outs. A heat shield is not included, and this kit does not include a separate valve actuator since it reuses the OEM unit.
