CORSA Sport 3.0" Cat-Back Exhaust with 4.5" Straight Tips (21255) - 2024-2026 Mustang GT Coupe
Give your S650 Mustang GT a deeper, more aggressive exhaust note without stepping all the way up to CORSA's Xtreme sound level with the CORSA Sport 3.0-Inch Cat-Back Exhaust System. Engineered specifically for the 7th Generation Mustang and its 5.0L Coyote V8, the Sport system combines custom-tuned mufflers with precision acoustic engineering to deliver a noticeable increase in exhaust volume while maintaining a comfortable driving experience during everyday cruising.
The Sport configuration produces approximately 8 dB more sound than the factory exhaust, bringing the Coyote V8 to life during cold starts and acceleration. CORSA's best-in-class No DRONE RSC® technology is engineered to control unwanted frequencies inside the cabin, allowing drivers to enjoy a more aggressive exterior exhaust note without the intrusive drone commonly associated with performance exhaust systems.

Sport Sound
CORSA's Sport configuration is an excellent choice for Mustang owners who want a more authoritative Coyote V8 exhaust note while retaining a refined character for regular street driving. Producing approximately 8 dB more sound than the factory exhaust, the Sport system adds noticeable volume and attitude during startup and acceleration without reaching the more extreme sound level of CORSA's Xtreme configuration.
At cruising speeds, CORSA's No DRONE RSC® technology works to eliminate unwanted cabin resonance. The result is a performance exhaust that can deliver aggressive sound when you're on the throttle while remaining comfortable during highway cruising and everyday driving.
Performance & Flow
The system utilizes a straight-through muffler design that increases exhaust flow by 48%, helping reduce restriction and allowing the 5.0L Coyote V8 to breathe more freely. The freer-flowing design also helps drivers maximize the benefits of supporting performance modifications, making the CORSA Sport Cat-Back a strong addition to both stock and modified S650 Mustang GT builds.
Construction & Styling
CORSA constructs this Cat-Back system from durable 304 stainless steel for long-lasting performance and corrosion resistance. The dual rear exhaust exits are finished with large 4.5-inch polished stainless steel dual-wall straight-cut tips, giving the rear of the Mustang a clean, aggressive appearance that complements the system's performance-focused sound.
CORSA Performance exhaust systems are engineered and manufactured in Berea, Ohio, combining American-made construction with extensive acoustic tuning and performance-focused engineering. This system is also backed by CORSA's Lifetime Warranty for added confidence in your exhaust upgrade.
