Description
Overview
The Flowmaster Signature Series Cat-back Exhaust System Kit is engineered specifically for 2024 to 2026 GM 1500 trucks equipped with the 6.2-liter engine, giving Silverado and Sierra owners a purpose-built way to add sound and performance. Built from durable 304 stainless steel, this catback exhaust is designed for years of trouble-free service while delivering the aggressive-yet-moderate tone the Signature Series is known for. Whether you’re ready to shop for exhaust upgrades or comparing a Flowmaster performance exhaust against Borla exhaust, Corsa exhaust, or MagnaFlow exhaust options, this kit is a complete, cohesive package.
Sound, Power & Active Valve Control
At the heart of the system is a specialty tuned Signature Series muffler fed by a 3.50-inch inlet pipe, producing great sound and maximum performance. Dual 2.5-inch mandrel-bent tailpipes exit through the factory bumper cut-out locations and retain the factory exhaust bezel for a clean, OEM-integrated look. Best of all, this exhaust system includes active valve control with an integrated turndown, letting you command the factory valve right from the dash using your drive modes. Run the valve closed in Normal for a quieter ride, or open it up in Sport or Off-Road mode for full-volume sound on demand.
This is a performance exhaust you can feel as well as hear. On the dyno, the system delivers max gains of 15 horsepower and 13 lb-ft of torque at the rear wheels, adding real, usable power to your 6.2L truck. It’s a car exhaust and truck exhaust upgrade built to work with your factory setup rather than fight it.
