Product Description

The CORSA 21127BLK is the Sport-level dual rear exit cat-back exhaust system for the 2021-2023 Chevrolet Tahoe and GMC Yukon equipped with the 5.3L EcoTec3 V8 and the factory Dual Rear Exit exhaust configuration. Tuned specifically for the tone and harmonics of the 5.3L V8 in the new-generation GM full-size SUV platform, the system eliminates the stock system's restrictive flow-operated valves and replaces them with a straight-through RSC muffler design, unlocking up to 20% additional horsepower and torque below 5,000 RPM. The result is a distinct, authoritative rumble at idle and a controlled, aggressive tone under acceleration - all without interior drone at highway speeds.

Built with a 3.0-inch T-304 stainless steel head pipe and muffler that steps down to 2.75-inch tail pipes, the system maintains excellent exhaust velocity while optimizing flow. The twin 4.0-inch slash-cut black PVD dual-wall Pro-Series tips provide a clean, blacked-out look at the rear of the vehicle. Installation is a bolt-on process with no cutting or welding required. This system is designed for vehicles with factory Dual Rear Exit exhaust - SSE-equipped vehicles require additional OEM GM components. Backed by CORSA's limited lifetime warranty.
