Product Description
Flowmaster's American Thunder Cat-back exhaust system for the 2024 to 2026 GM 1500 trucks with the 6.2-liter engine is a great way to customize your Silverado or Sierra to your personality. This performance exhaust system fits both 2/4 Wheel drive models and is manufactured from 409 stainless steel for years of trouble-free service and performance. Features include a 3.50-inch inlet pipe leading into a specialty tuned 50 Series HD style muffler for great sound and maximum performance. This cat-back system has dual 2.5-inch mandrel-bent tailpipes that exit in the bumper cut-out locations, with custom quad exit 4.0-inch black ceramic tips for a great performance look. Included in this cat-back system is active valve control with an integrated turndown.
This allows you to control the factory valve from the dash with the different drive modes for full control of your sound level. Run the valve closed in the Normal drive mode, or open the valve in Sport or Off-Road mode for maximum sound. Max dyno gains of 15 hp and 13 lb-ft at the rear wheels deliver power you can feel. These systems use all the factory hanger locations and connections for an easy installation that you can do at home. Kit include installation instructions and all necessary hardware. Backed by Flowmaster's Lifetime Limited Warranty.
