Frequently Asked Questions
What is the CORSA 14749BLK?The CORSA 14749BLK 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 matte black PVD Pro-Series tips and CORSA RSC technology for deep Denali-worthy performance sound without highway drone.
How does the 14749BLK differ from the 14749?Both are identical Sport cat-backs with the same RSC tuning, 3.0-inch T304 construction, and dual rear exit. The only difference is tip finish: the 14749 has polished stainless tips; the 14749BLK has matte black PVD-coated tips.
Does the 14749BLK fit the Yukon Denali and Yukon XL Denali?Yes. The CORSA 14749BLK fits the 2015-2019 GMC Yukon Denali and 2015-2020 GMC Yukon XL Denali with the 6.2L V8 engine.
Is this drone-free at highway speeds?Yes. CORSA's RSC technology is specifically calibrated to the 6.2L V8 to cancel the resonance frequency that causes drone, keeping the Denali comfortable on the highway while sounding aggressive under acceleration.
Will the black tips hold up under daily driving?Yes. The matte black PVD coating on T304 stainless steel is heat-resistant and designed for durability under normal driving conditions. Periodic cleaning helps preserve the finish.
Does this require any modifications or tuning?No. The CORSA 14749BLK is a direct bolt-on replacement. No cutting, welding, or ECU tuning is required.
Is this compatible with the factory active exhaust?Most GMC Yukon Denali models in the 2015-2020 range do not have an active exhaust valve. If your vehicle has one, verify compatibility with CORSA before purchasing.
How long does installation take?Most installations complete in 1 to 2 hours with basic hand tools.
