Corsa Sport 3.5" Cat-Back Dual Rear Exit Exhaust with Black Tips (21130BLK) - 2021-2025 Suburban / Yukon XL 6.2L V8
Give your 2021-2025 Chevrolet Suburban, GMC Yukon XL, or GMC Yukon Denali XL 6.2L V8 a more aggressive exhaust note and a bold performance appearance with the Corsa Sport 3.5" Cat-Back Exhaust System. Engineered specifically for GM's full-size SUVs, the 21130BLK combines Corsa's exclusive Reflective Sound Cancellation (RSC) No Drone Technology with a freer-flowing exhaust design, premium 304 stainless steel construction, and twin 4.0" black Pro-Series tips.
The Corsa Sport system delivers an aggressive exhaust note under acceleration while maintaining a quiet, drone-free cabin at cruising speeds. By eliminating the restrictive flow-operated valves used in the factory exhaust, Corsa allows the 6.2L V8 to breathe more freely. Corsa reports improvements of up to 20% horsepower and 20% torque under the curve while also providing the potential for improved fuel economy.
Sport Sound with Corsa RSC No Drone Technology
Corsa's Reflective Sound Cancellation (RSC) No Drone Technology is engineered to provide the aggressive sound enthusiasts want without the unwanted in-cabin frequencies that can make conventional performance exhaust systems uncomfortable during everyday driving.
Corsa's acoustic engineers use RSC technology to target and eliminate drone-inducing frequencies while retaining the desirable frequencies that create an aggressive performance exhaust note. Under acceleration, the 6.2L V8 delivers a stronger Sport sound. At cruising speeds, the system is designed to maintain a quiet, drone-free cabin.
This balance is particularly valuable in a full-size SUV such as the Suburban or Yukon XL, allowing owners to enjoy a performance exhaust without sacrificing highway comfort or long-distance drivability.
Improved Exhaust Flow
The stock exhaust system incorporates restrictive flow-operated valves. Corsa's Cat-Back design eliminates these valves, allowing exhaust gases to move more freely through the system and reducing unnecessary restriction.
The freer-flowing configuration works with Corsa's straight-through muffler architecture to improve exhaust flow. Rather than relying on restrictive muffler construction to control unwanted noise, Corsa uses RSC acoustic technology to address drone-inducing frequencies.
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 a claim of a 20% increase in peak horsepower or peak torque. Vehicle torque is limited.
By eliminating restrictive factory flow-operated valves and allowing the engine to breathe more freely, the system can also contribute to improved fuel economy.
3.5" Cat-Back Exhaust Design
The Corsa 21130BLK features a 3.5" diameter head pipe and muffler section before transitioning to 2.75" diameter tail pipes. This large-diameter configuration provides the flow capacity needed for the 6.2L V8 while supporting the Sport sound characteristics Corsa engineered specifically for GM's full-size SUV platform.
The system uses a dual rear exit configuration and is designed around vehicles originally equipped with a factory dual rear exit exhaust. Vehicles equipped from the factory with a single side exit exhaust require additional GM components to complete the conversion to Corsa's dual rear exit configuration.
Straight-Through Muffler Design
Corsa combines a straight-through muffler design with its RSC acoustic technology to balance performance, sound, and cabin comfort. The straight-through architecture promotes exhaust flow while RSC technology controls the frequencies responsible for unwanted interior drone.
This approach allows the 6.2L V8 to produce an aggressive Sport exhaust note under throttle without creating constant low-frequency resonance inside the cabin during steady-speed cruising.
304 Stainless Steel Construction
The Corsa Cat-Back system is manufactured from 304 stainless steel for excellent durability and corrosion resistance. The premium stainless construction provides a strong foundation for the complete system and is designed for the demands of regular street use.
Twin 4.0" Black Pro-Series Tips
The 21130BLK finishes its dual rear exit configuration with twin 4.0" black Corsa Pro-Series exhaust tips. The Pro-Series tips feature dual-wall construction with a slash-cut profile, giving the rear of the Suburban or Yukon XL a more aggressive appearance to complement the upgraded exhaust note.
The black finish provides a darker, more understated alternative to the polished tips used on Corsa part number 21130 while retaining the same twin 4.0" Pro-Series design.
Designed for 134.1" Wheelbase GM SUVs
The Corsa 21130BLK is specifically designed for compatible 2021-2025 Chevrolet Suburban, GMC Yukon XL, and GMC Yukon Denali XL models equipped with the 6.2L V8, 134.1" wheelbase, and factory dual rear exit exhaust.
Vehicles originally equipped with a single side exit exhaust can be converted for use with Corsa's dual rear exit system, but additional GM components are required. Corsa recommends verifying every required component and quantity for the specific vehicle before purchasing parts or beginning installation.
