Corsa Xtreme 3.0" Cat-Back Exhaust with 4.5" Polished Slash-Cut Tips (21250) - 2024-2026 Mustang GT Coupe 5.0L
Unleash a substantially more aggressive exhaust note from your 2024-2026 Ford Mustang GT with the Corsa Xtreme 3.0" Cat-Back Exhaust System. Engineered specifically for the 7th Generation S650 Mustang and its Coyote 5.0L V8, this system combines precision acoustic tuning, 304 stainless steel construction, increased exhaust flow, and Corsa's best-in-class No DRONE RSC Technology for an exhaust that can deliver thunderous sound on command while remaining quiet and comfortable at cruise.
This 21250 system is designed specifically for Mustang GT Fastback/Coupe models without the factory Active Valve exhaust. With the Xtreme sound level, dual rear exits, and 4.5" polished Pro-Series slash-cut tips, it delivers an aggressive combination of sound, performance capability, and appearance while retaining the refined cruising characteristics Corsa is known for.
Xtreme Sound - 16 dB Louder Than Stock
Corsa's Xtreme sound level is engineered for Mustang owners who want to hear the Coyote V8. Precision acoustic tuning unlocks an additional 16 dB of sound compared with the stock exhaust, creating a thunderous exhaust note during cold starts and heavy acceleration.
Despite the dramatic increase in exterior volume, the system is engineered to maintain a quiet, drone-free cabin while cruising. This combination gives the Mustang an aggressive personality when the throttle opens without forcing the driver to live with unwanted resonance during normal driving.
Best-in-Class No DRONE RSC Technology
Corsa incorporates its best-in-class No DRONE RSC technology to control unwanted frequencies that can otherwise create irritating cabin drone. The system is acoustically tuned specifically around the 7th Generation Mustang Coyote V8, allowing the exhaust to deliver its aggressive Xtreme character under acceleration while maintaining a more comfortable cabin at cruise.
48% Increased Exhaust Flow
The Corsa S650 Mustang exhaust utilizes a straight-through muffler design engineered to increase exhaust flow by 48%. The freer-flowing design helps drivers maximize the benefits of additional performance modifications while giving the Coyote V8 a less restrictive exhaust path.
Combined with the 3.0" piping, the straight-through muffler architecture makes this system an excellent foundation for enthusiasts looking to build beyond a stock Mustang while still maintaining the sound control and street manners engineered into the Corsa system.
3.0" 304 Stainless Steel Construction
The system is constructed from 3.0" 304 stainless steel for excellent durability and corrosion resistance. Corsa pairs the premium stainless construction with custom-tuned mufflers developed specifically for the S650 Mustang GT platform rather than relying on a universal muffler design.
The complete Cat-Back system uses a dual rear exit configuration and also reduces weight by 16 lbs compared with the stock exhaust system.
4.5" Polished Pro-Series Slash-Cut Tips
Finishing the system are impressive 4.5" polished Pro-Series stainless steel exhaust tips. Each tip features a dual-wall, slash-cut design that gives the rear of the S650 Mustang GT a clean performance appearance while filling out the factory exhaust openings with a larger, more aggressive tip design.
Corsa's S650 Mustang exhaust collection is offered with multiple tip designs, including slash-cut, straight-cut, and carbon fiber options. This 21250 configuration specifically includes the polished dual-wall Pro-Series slash-cut tips.
Engineered Specifically for the S650 Mustang GT
Rather than simply increasing exhaust volume, Corsa engineered and acoustically tuned this system around the characteristics of the 7th Generation Mustang Coyote V8. The result combines a significant increase in sound under acceleration, improved exhaust flow, reduced weight, and drone control into one complete Cat-Back system.
This configuration is intended specifically for Mustang GT Fastback/Coupe models that are not equipped with the factory Active Valve exhaust system.
American Made and Lifetime Warranty
