Corsa Sport 3.5" Cat-Back Dual Rear Exit Exhaust (21131) - 2021-2025 Cadillac Escalade 6.2L V8
Give your 2021-2025 Cadillac Escalade 6.2L V8 a deeper, more aggressive exhaust note without sacrificing the refined cruising experience expected from a full-size luxury SUV. The Corsa Sport 3.5" Cat-Back Exhaust System combines a freer-flowing exhaust design with Corsa's exclusive Reflective Sound Cancellation (RSC) No Drone Technology to deliver an aggressive sound under acceleration while maintaining a quiet, drone-free cabin at cruising speeds.
Designed specifically around GM's full-size SUV platform, the Corsa 21131 eliminates the restrictive flow-operated valves found in the stock exhaust system, allowing exhaust gases to move more freely. Corsa reports improvements of up to 20% horsepower and 20% torque under the curve, while the freer-flowing configuration can also improve fuel economy. The dual rear exit system is designed without aftermarket tips and instead reuses the Escalade's factory exhaust bezels for a clean, OEM-integrated appearance.
Corsa Sport Exhaust Sound
The Sport sound level gives the Escalade's 6.2L V8 a more aggressive personality without turning everyday driving into a constant battle with unwanted exhaust noise. Under acceleration, the system delivers the stronger performance exhaust note expected from a Corsa system. Once the vehicle settles into a steady cruise, Corsa's acoustic engineering works to keep the cabin quiet and comfortable.
This balance makes the 21131 particularly well suited to the Escalade, delivering a noticeable performance sound when you want to hear the 6.2L V8 while preserving the comfort expected during highway driving and longer trips.
Exclusive RSC No Drone Technology
Corsa's Reflective Sound Cancellation (RSC) No Drone Technology is engineered specifically to eliminate the frequencies responsible for unwanted in-cabin exhaust drone. Rather than simply restricting exhaust flow to control noise, RSC technology acoustically targets drone-inducing frequencies while allowing the desirable performance sound of the engine to remain.
The result is an aggressive exhaust note during acceleration combined with a quiet, drone-free cabin at cruising speeds. This allows the driver to enjoy a stronger 6.2L V8 exhaust note without compromising everyday drivability.
Improved Exhaust Flow
The factory exhaust incorporates restrictive flow-operated valves. Corsa's Cat-Back system eliminates these valves, allowing the exhaust to breathe more freely and reducing unnecessary restriction in the system.
Combined with its straight-through muffler design, the Corsa system is engineered to support improved exhaust flow while RSC technology handles unwanted sound frequencies acoustically rather than depending on a restrictive muffler design.
Up to 20% Horsepower and Torque Improvement Under the Curve
Corsa reports improvements of up to 20% horsepower and 20% torque under the curve with its GM SUV Cat-Back exhaust design. These figures represent improvements measured under the performance curve rather than claims of a 20% increase in peak horsepower or peak torque. Vehicle torque is limited.
The reduction in exhaust restriction can also contribute to improved fuel economy by allowing the engine to move exhaust gases more efficiently.
3.5" Cat-Back Configuration
The Corsa 21131 features a 3.5" Cat-Back exhaust configuration with a 3.5" diameter head pipe and muffler section before transitioning into the dual rear tail pipes. This large-diameter exhaust architecture is designed around the airflow and sound characteristics of the Escalade's 6.2L V8.
Straight-Through Muffler Design
Corsa utilizes a straight-through muffler design to promote exhaust flow while its RSC acoustic technology controls unwanted in-cabin frequencies. This approach allows the system to deliver the aggressive Sport exhaust note under throttle without relying on heavily restrictive internal muffler construction to maintain cabin comfort.
304 Stainless Steel Construction
The exhaust system is manufactured from 304 stainless steel for excellent durability and corrosion resistance. The premium stainless construction is designed to withstand regular street use while providing the long-term durability expected from a performance exhaust upgrade.
Dual Rear Exit with Factory Bezels
The 21131 uses a dual rear exit configuration designed specifically to integrate with the Cadillac Escalade's rear fascia. No aftermarket exhaust tips are included with the system. Instead, the exhaust is designed to reuse the vehicle's factory exhaust bezels.
Retaining the factory bezels preserves the Escalade's clean OEM exterior appearance while providing the sound and flow benefits of the Corsa performance exhaust underneath the vehicle.
