Corsa Sport 3.5" Cat-Back Dual Rear Exit Exhaust with Polished Tips (21130) - 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 performance-focused appearance with the Corsa Sport 3.5" Cat-Back Exhaust System. Engineered specifically for GM's full-size SUVs, the 21130 combines Corsa's exclusive Reflective Sound Cancellation (RSC) No Drone Technology with a freer-flowing exhaust design, premium 304 stainless steel construction, and polished twin 4.0" Pro-Series tips.
The Corsa Sport system delivers a strong, aggressive exhaust note when accelerating 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 designed to provide the sound of a performance exhaust without the unwanted in-cabin frequencies that can make traditional aftermarket exhaust systems tiring during everyday driving.
Corsa's acoustic engineers use RSC technology to target and eliminate drone-inducing frequencies while preserving the aggressive frequencies drivers want to hear. The result is a strong Sport exhaust note during acceleration paired with a quiet, comfortable cabin when cruising.
This combination is especially valuable on a full-size SUV such as the Suburban or Yukon XL, where highway comfort and long-distance drivability remain important even after upgrading the exhaust system.
Improved Exhaust Flow
The factory 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.
The freer-flowing design works with Corsa's straight-through muffler architecture to reduce unnecessary exhaust restriction. Instead of relying on restrictive internal muffler construction to control unwanted sound, Corsa uses RSC acoustic technology to manage drone while maintaining exhaust flow.
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 system. These results 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 reducing exhaust restriction and allowing the 6.2L V8 to breathe more freely, the system can also contribute to improved fuel economy.
3.5" Cat-Back Exhaust Design
The Corsa 21130 features a 3.5" diameter head pipe and muffler section before transitioning to 2.75" diameter tail pipes. This configuration provides the flow capacity needed for the 6.2L V8 while supporting the 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. Additional factory GM components are required when converting a vehicle originally equipped with a single side exit exhaust.
Straight-Through Muffler Design
Corsa combines its straight-through muffler construction with RSC acoustic technology to balance performance, sound, and cabin comfort. The straight-through design promotes exhaust flow while RSC controls the frequencies responsible for unwanted drone.
This allows the 6.2L V8 to deliver an aggressive exhaust note when accelerating without creating a constant low-frequency resonance inside the cabin at cruising speeds.
304 Stainless Steel Construction
The Corsa Cat-Back system is manufactured from 304 stainless steel for excellent durability and corrosion resistance. This premium construction is designed to withstand regular street use while providing the long-term durability expected from a high-quality performance exhaust system.
Polished Twin 4.0" Pro-Series Tips
The 21130 finishes the dual rear exit system with polished twin 4.0" Corsa Pro-Series exhaust tips. The Pro-Series tips feature a dual-wall construction and slash-cut profile, giving the rear of the Suburban or Yukon XL a clean, performance-oriented appearance that complements the upgraded exhaust note.
Designed for 134.1" Wheelbase GM SUVs
The Corsa 21130 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.
Owners of vehicles originally equipped with a single side exit exhaust can install Corsa's dual rear exit system, but additional GM components are required to complete the conversion. Corsa recommends verifying every required part and quantity for the specific vehicle before purchasing the exhaust system or conversion components.
