The Gibson Black Elite single cat-back for 2015–2018 GMC Yukon XL SLE 5.3L uses 2.25in routing to refine tone and flow for larger SUVs. A Superflow stainless muffler and mandrel-bent tubing give a deeper, controlled note while a black-finish T-304 tip adds contrast. It includes factory-style hangers for an easy bolt-on fit, minimizes interior drone, and carries a lifetime limited warranty.
