Corsa Sport 3.0" Cat-Back Exhaust with 4.5" Black Slash-Cut Tips (21254BLK) - 2024-2026 Mustang GT Coupe 5.0L
Give your 2024-2026 Ford Mustang GT a more aggressive Coyote V8 exhaust note while maintaining comfortable cruising characteristics with the Corsa Sport 3.0" Cat-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 for a refined performance exhaust upgrade.
This 21254BLK system features Corsa's Sport sound level and is designed specifically for Mustang GT Fastback/Coupe models without the factory Active Valve exhaust. With a dual rear exit configuration and 4.5" black Pro-Series slash-cut tips, the system upgrades the sound, flow, weight, and appearance of the S650 Mustang while retaining a quiet, drone-free cabin at cruise.
Sport Sound - 8 dB Louder Than Stock
Corsa rates the Sport Cat-Back at 8 dB louder than the stock Mustang GT exhaust. The Sport sound level provides a noticeable increase in Coyote V8 presence, giving the Mustang a stronger exhaust note while remaining more restrained than Corsa's Xtreme option.
For drivers looking for the most aggressive option in the lineup, Corsa's Xtreme Cat-Back unlocks 16+ dB of sound over stock and creates thunderous exhaust notes during cold starts and heavy acceleration. The Sport configuration is an excellent choice for enthusiasts who want an aggressive performance exhaust while maintaining a more moderate overall sound level.
Best-in-Class No DRONE RSC Technology
Corsa's S650 Mustang exhaust collection features best-in-class No DRONE RSC technology to control unwanted frequencies and resonance inside the cabin. The custom-tuned mufflers are engineered specifically around the characteristics of the 7th Generation Mustang Coyote V8, allowing the exhaust to deliver an aggressive exterior sound while maintaining a quiet, drone-free cabin at cruise.
This application-specific acoustic engineering lets drivers enjoy the sound of the Coyote V8 when accelerating without having to tolerate unwanted exhaust drone during highway cruising and everyday driving.
48% Increased Exhaust Flow
Corsa utilizes a straight-through muffler design that increases exhaust flow by 48%. The freer-flowing exhaust design allows drivers to maximize the benefits of additional performance modifications while providing the Coyote V8 with a less restrictive exhaust path.
Combined with the full 3.0" Cat-Back design, the increased flow makes the Corsa system a strong foundation for Mustang owners who plan to add other performance modifications while retaining Corsa's application-specific sound control.
3.0" 304 Stainless Steel Construction
The Corsa Sport Cat-Back features 3.0" 304 stainless steel construction for excellent durability and corrosion resistance. Corsa combines its premium stainless steel construction with custom-tuned mufflers engineered specifically for the S650 Mustang GT rather than relying on a universal muffler configuration.
The complete system uses a dual rear exit layout and provides a 12 lb weight savings compared with the stock exhaust system, reducing weight while upgrading the Mustang's exhaust sound, flow, and appearance.
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 designs, including slash-cut, straight-cut, and carbon fiber options. This 21254BLK configuration specifically includes the black 4.5" dual-wall Pro-Series slash-cut tips.
Engineered Specifically for the S650 Mustang GT
Corsa engineered its 3.0" Cat-Back collection specifically around the 7th Generation Mustang Coyote V8. Custom-tuned mufflers, precision acoustic engineering, increased exhaust flow, and premium stainless steel construction work together to create a system designed around the performance and sound characteristics of the S650 Mustang GT.
Corsa offers both Sport and Xtreme sound levels within the S650 Mustang Cat-Back lineup. This 21254BLK configuration features the Sport sound level for drivers looking for a significant improvement in exhaust character without stepping up to the substantially louder Xtreme configuration.
