Corsa Sport 3.0" Axle-Back Exhaust with 4.5" Black Slash-Cut Tips (21252BLK) - 2024-2026 Mustang GT Coupe 5.0L
Give your 2024-2026 Ford Mustang GT a more aggressive Coyote V8 exhaust note without sacrificing comfortable cruising with the Corsa Sport 3.0" Axle-Back Exhaust System. Engineered specifically for the 7th Generation S650 Mustang GT, this system combines custom-tuned mufflers, 304 stainless steel construction, increased exhaust flow, and Corsa's best-in-class No DRONE RSC Technology to deliver an aggressive sound when you want it while maintaining a quiet, drone-free cabin at cruise.
This 21252BLK Sport Axle-Back is designed specifically for Mustang GT Fastback/Coupe models without factory Active Valve exhaust. It bolts directly to the stock resonated mid-pipe, making it an excellent option for drivers who want to upgrade the sound, appearance, and exhaust flow of their Mustang while retaining the factory mid-pipe.
Sport Sound - 7-8 dB Louder Than Stock
Corsa's Sport sound level provides a noticeable increase in volume without taking the Mustang to an excessively aggressive sound level. Corsa rates the Sport Axle-Back at approximately 7-8 dB louder than the stock exhaust, producing moderately aggressive exhaust notes that turn heads during cold starts and heavy acceleration.
At cruising speeds, the system is engineered to remain quiet and drone-free, giving drivers a balance between an aggressive Coyote V8 sound under throttle and comfortable cabin characteristics during everyday driving.
Best-in-Class No DRONE RSC Technology
Corsa incorporates its best-in-class No DRONE RSC technology into the Sport Axle-Back to manage unwanted frequencies and resonance inside the cabin. The custom-tuned mufflers were engineered specifically around the characteristics of the 7th Generation Mustang Coyote V8, allowing the exhaust to deliver a more aggressive exterior sound without creating unwanted drone at cruise.
Bolts Directly to the Stock Resonated Mid-Pipe
The Corsa Sport Axle-Back is engineered to bolt directly to the factory resonated mid-pipe. This allows Mustang GT owners to retain the stock resonated center section while upgrading the rear portion of the exhaust with Corsa's application-specific mufflers and 3.0" exhaust components.
For drivers who want a meaningful sound upgrade without replacing the entire Cat-Back exhaust system, the Axle-Back configuration provides a targeted upgrade to the rear exhaust while retaining more of the factory system.
46% Increased Exhaust Flow
Corsa utilizes a straight-through muffler design that increases exhaust flow by 46%. The freer-flowing design allows drivers to maximize the benefits of additional performance modifications while giving the Coyote V8 a less restrictive path through the rear section of the exhaust.
Along with the increased flow, the Corsa Sport Axle-Back provides a 9 lb weight savings compared with the stock exhaust components.
3.0" 304 Stainless Steel Construction
The system features 3.0" 304 stainless steel construction for excellent durability and corrosion resistance. Corsa combines the premium stainless steel construction with custom-tuned mufflers engineered specifically for the S650 Mustang GT rather than relying on a universal muffler design.
The system uses a dual rear exit configuration and is designed to integrate directly with the factory resonated mid-pipe on compatible non-Active Valve Mustang GT models.
4.5" Black Pro-Series Slash-Cut Tips
Finishing the system are 4.5" black Pro-Series stainless steel exhaust tips. Each tip features dual-wall construction and a slash-cut design, providing a larger, darker, and more aggressive appearance at the rear of the S650 Mustang GT.
Corsa's S650 Mustang exhaust collection is available with multiple tip styles, including slash-cut, straight-cut, and carbon fiber options. This 21252BLK configuration specifically includes the black 4.5" dual-wall Pro-Series slash-cut tips.
Engineered Specifically for the S650 Mustang GT
Corsa designed and acoustically tuned the Sport Axle-Back specifically around the 7th Generation Mustang Coyote V8. Rather than simply making the exhaust louder, the system combines application-specific acoustic tuning, increased flow, reduced weight, premium construction, and drone control to create a more refined performance exhaust upgrade.
Corsa lists both Sport and Touring sound levels within its S650 Mustang Axle-Back lineup, giving owners the ability to select a sound profile that suits their driving preferences. This 21252BLK system features the more aggressive Sport sound level.
