CORSA Xtreme 3.0" Cat-Back Exhaust with 4.5" Straight Tips (21251BLK) - 2024-2026 Mustang GT Coupe
Unleash a significantly more aggressive exhaust note from your S650 Mustang GT with the CORSA Xtreme 3.0-Inch Cat-Back Exhaust System. Engineered specifically around the 7th Generation Mustang's 5.0L Coyote V8, this system uses custom-tuned mufflers and precision acoustic tuning to deliver a thunderous exhaust note when you want it. The Xtreme configuration produces more than 16 dB of additional sound compared to stock, bringing serious presence to cold starts and heavy acceleration while maintaining a comfortable, drone-free cabin during cruising.
CORSA's best-in-class No DRONE RSC® technology helps control unwanted frequencies inside the cabin without sacrificing the aggressive character enthusiasts expect from the Xtreme system. A straight-through muffler design increases exhaust flow by 48%, making the system an excellent complement to additional performance modifications while allowing the Coyote V8 to breathe more freely.
