CORSA Sport 3.0" Cat-Back Exhaust with 4.5" Carbon Fiber Polished Tips (21255CF) - 2024-2026 Mustang GT Coupe
Give your S650 Mustang GT a deeper, more aggressive exhaust note with premium carbon fiber styling using 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 the refinement needed for everyday street driving.
The Sport configuration produces approximately 8 dB more sound than the factory exhaust, bringing out more of the Coyote V8's character 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 an aggressive exterior exhaust note while maintaining a quiet, drone-free environment at cruising speeds.

Sport Sound
CORSA's Sport configuration is designed for Mustang owners who want more exhaust presence while retaining a refined character for regular street use. Producing approximately 8 dB more sound than the factory exhaust, the Sport system delivers a stronger, more authoritative Coyote V8 note during startup and acceleration without reaching the higher volume of CORSA's Xtreme configuration.
At cruising speeds, CORSA's No DRONE RSC® technology works to eliminate unwanted cabin resonance. This allows the exhaust to deliver an aggressive sound when you're on the throttle while maintaining a comfortable, drone-free cabin during highway cruising and everyday driving.
Performance & Flow
CORSA 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 increased flow also allows drivers to better maximize the benefits of supporting performance modifications, making this Sport Cat-Back a strong addition to both stock and modified S650 Mustang GT builds.
Carbon Fiber Polished Tips
This configuration features CORSA's 4.5-inch carbon fiber exhaust tips for a premium performance-inspired finishing touch. Each tip incorporates a dual-wall straight-cut design with a polished stainless steel inner cone, combining the distinctive appearance of carbon fiber with a bright polished accent. The oversized 4.5-inch outlets complement the modern rear styling of the S650 Mustang while providing a more distinctive appearance than traditional stainless steel tips.
Construction & Durability
The Cat-Back system is constructed from durable 304 stainless steel for long-lasting performance and corrosion resistance. CORSA Performance exhaust systems are engineered and manufactured in Berea, Ohio, combining American-made construction with extensive acoustic tuning and performance-focused engineering. The system is also backed by CORSA's Lifetime Warranty for added confidence in your exhaust upgrade.
