Premium Denali Sound Elevated by RSC-Tuned Sport Performance
The CORSA 14749 is a 3.0-inch Sport cat-back exhaust system built for the 2015-2020 GMC Yukon Denali and Yukon XL Denali with the 6.2L V8 engine. The Denali's 6.2L platform is the most powerful engine option in the full-size GM SUV lineup, and CORSA engineers tuned the 14749's RSC technology specifically to match its character. The result is an authoritative, deep Sport exhaust note that reflects the Denali's premium positioning without introducing any highway drone. The system routes to twin 4.0-inch polished Pro-Series tips at dual rear exits, providing a visual upgrade that complements the Denali's premium appearance package.

Frequently Asked Questions
What is the CORSA 14749?The CORSA 14749 is a 3.0-inch Sport cat-back exhaust system for the 2015-2020 GMC Yukon Denali and Yukon XL Denali with the 6.2L V8 engine, featuring twin 4.0-inch polished Pro-Series tips and CORSA RSC technology for an authoritative performance exhaust note without highway drone.
Does the 14749 fit the standard Yukon or only the Denali trim?The CORSA 14749 is specifically designed for the Denali and Yukon XL Denali with the 6.2L V8 engine. The 5.3L V8 Yukon and Yukon XL in non-Denali trims use the 14748 fitment.
Is the CORSA 14749 drone-free at highway speeds?Yes. CORSA's RSC technology eliminates the drone frequency specific to the 6.2L V8 at highway RPM, making the 14749 comfortable for long-distance driving while delivering Sport-level sound under throttle.
Does installation require cutting or welding?No. The CORSA 14749 is a direct bolt-on replacement at factory mounting points with no cutting or welding required.
What is the difference between 14749 and 14749BLK?Both are identical Sport cat-back systems. The 14749 features polished stainless tips; the 14749BLK features matte black PVD-coated tips.
Can the 14749 be installed without a lift?The Yukon XL has sufficient ground clearance that most experienced DIYers complete the install on jack stands, but access to a lift makes the job significantly easier.
Does this work with the factory active exhaust on the Denali?Most Denali 6.2L trims in this generation do not feature a factory active exhaust NPP valve. If your vehicle has an active exhaust valve, consult CORSA before purchasing to verify compatibility.
What is the warranty on the CORSA 14749?CORSA provides a limited lifetime warranty on the 14749 against defects in materials and workmanship when purchased from an authorized dealer and used in normal on-road conditions.
