Product Description

The Gibson 65640 Dual Sport cat-back exhaust system is designed for 2010-2014 Chevrolet Tahoe and GMC Yukon models equipped with the 5.3L V8. The system uses 2.25-inch 409 stainless steel mandrel-bent tubing and a baffled, chambered SuperFlow muffler to improve exhaust flow while producing a deeper, more aggressive exhaust sound.

The system uses a single muffler with dual outlets and exits behind the rear tires through two polished 3.50-inch T-304 stainless steel slash-cut tips. Factory-style hangers and installation hardware are included, with the system designed for a bolt-on installation using the factory exhaust mounting points. It is suitable for applicable 2WD and 4WD configurations and is engineered around the factory-stock vehicle configuration.
