The Gibson Dual Split cat-back exhaust for 2019–2024 GMC Sierra 1500 Denali (6.2L) is built to last with stainless construction and factory-location exit tips. It lowers backpressure to increase torque and horsepower (typical gains ~18–20 hp) while offering an aggressive throaty tone. Mandrel-bent tubing and a baffled muffler provide a controlled sound, and the bolt-on installation uses stainless band clamps with no welding required.
