GMC Sierra Performance Exhaust - Dual Exit - Flowmaster - Cat Back + Flow FX - 24-26 fits 2024-2026 Sierra 1500 6.2L models. It adds a deep, performance tone and responsive power in a direct-fit package.
Constructed from 16-gauge 409 stainless, this cat-back runs a 3.5 in inlet into a tuned Flow FX muffler, then splits to dual 2.5 in mandrel-bent tails that exit at the bumper cutouts and retain the factory bezel. The active valve with integrated turndown works with factory drive modes to manage sound—closed in Normal, open in Sport or Off-Road. It fits 2WD/4WD, reuses stock hangers, and includes hardware and instructions. Dyno-tested gains reach up to 15 hp and 13 lb-ft at the wheels.
