10- GM Tahoe/Yukon 5.3 Cat Back Exhaust S.S.

The Gibson 10–14 GM Tahoe/Yukon 5.3 Cat Back Exhaust in Stainless Steel is a split-rear system engineered to replace factory exhaust from the catalytic converter rearward on 2010–2020 General Motors full-size SUVs. This cat-back exhaust delivers measurable improvements in flow characteristics and tone while maintaining compatibility with factory emissions hardware and oxygen sensors. The dual 3-inch stainless steel tips and 2.25-inch tailpipe design optimize backpressure management for 5.3-liter V8 performance without requiring engine tuning or modifications.

Construction combines stainless steel tubing with an aluminized protective layer, addressing the corrosion challenges that stock exhaust systems face over time. The 2.25-inch diameter maintains adequate scavenging velocity across the RPM range typical of 5.3-liter operation, while the expanded exit diameter through the dual tips reduces restriction in the final stage of gas evacuation. Weighing 59 pounds, the complete kit integrates with factory mounting points, eliminating the need for custom hangers or clearance modification on properly maintained vehicles.

This exhaust suits owners of Chevrolet Tahoe, Suburban, and GMC Yukon models seeking audible improvement without radical tone shift, as well as those addressing factory rust-through or performance decline in aging exhaust systems. The split-rear design allows independent service of either side, reducing replacement cost if future damage occurs. Installation typically requires basic hand tools and three to four hours; professional installation is available at most independent shops specializing in suspension and exhaust work for full-size trucks and SUVs.
