GMC Sierra 1500 Performance Exhaust - Flowmaster - FlowFX Cat-Back - 19-26. This bolt-on cat-back brings a deeper tone and freer flow to 5.3L, factory dual-exit Sierra 1500 models.
Crafted from 409 stainless steel, it runs a 3.00-inch inlet into a Flow FX straight-through muffler for a deep, moderate-to-aggressive note. Dual 2.50-inch mandrel-bent tails clear the spare and hitch and exit through the factory bumper bezels, keeping the OEM dual look. Reuses factory hangers and includes hardware and instructions for an at-home install. Max dyno gains recorded: 21 hp and 26 lb-ft at the wheels. Fits 2019–2026 Sierra 1500 Crew/Double Cab 5.3L with factory dual tails; 2WD/4WD. Does not fit Crew Cab 2WD with 2-piece driveshaft.
