Stealth V8 Performance Sound for the 2015-2020 Suburban and Yukon XL 5.3L
The CORSA 14748BLK is the black-tip variant of the Sport cat-back exhaust system built for the 2015-2020 Chevrolet Suburban and GMC Yukon XL with the 5.3L V8 engine. It shares the same 3.0-inch mandrel-bent T304 stainless steel platform and RSC-tuned Sport sound as the polished-tip 14748, but finishes with twin 4.0-inch matte black PVD Pro-Series tips that suit blacked-out, dark-themed, or tactical-inspired large SUV builds. CORSA's patented Reflective Sound Cancellation technology is calibrated to eliminate highway drone while delivering a confident V8 rumble under throttle.

Frequently Asked Questions
What is the CORSA 14748BLK?The CORSA 14748BLK is a 3.0-inch Sport cat-back exhaust system for the 2015-2020 Chevrolet Suburban and GMC Yukon XL 5.3L V8, featuring twin 4.0-inch matte black PVD Pro-Series tips and CORSA RSC technology for Sport-level V8 performance sound without highway drone.
What is the difference between 14748 and 14748BLK?Both are the same Sport-level cat-back system with identical RSC tuning and 3.0-inch T304 stainless construction. The only difference is tip finish: the 14748 uses polished stainless tips; the 14748BLK uses matte black PVD-coated tips.
Does the 14748BLK fit both the Suburban and Yukon XL?Yes. The CORSA 14748BLK fits both the 2015-2020 Chevrolet Suburban and 2015-2020 GMC Yukon XL with the 5.3L V8 engine in LS, LT, LTZ, Premier, SLE, and SLT trims.
Is this drone-free at highway speeds?Yes. CORSA's RSC technology is calibrated to the Suburban and Yukon XL 5.3L V8 platform to cancel the resonance frequencies that cause highway drone, keeping the cabin comfortable on long drives.
Will the matte black tips hold up over time?The matte black PVD finish on T304 stainless steel is heat-resistant and durable under normal driving conditions. Periodic cleaning preserves the finish.
Does this require any cutting, welding, or tuning?No. The CORSA 14748BLK is a direct bolt-on replacement using factory mounting points with no modifications required.
