Sport Sound Level
The CORSA Sport Axle-Back delivers a moderately aggressive exhaust note that makes the Coyote V8 more noticeable during cold starts and under heavy acceleration without making the Mustang uncomfortable during normal cruising. This Sport configuration is approximately 7-8 dB louder than the factory exhaust, providing a noticeable increase in volume while retaining a refined driving experience.
No DRONE RSC® Technology
CORSA's best-in-class No DRONE RSC® Technology is engineered to control the unwanted frequencies responsible for exhaust drone while preserving the aggressive frequencies enthusiasts want to hear. This allows the Sport Axle-Back to provide increased exterior sound during acceleration while maintaining a quiet, comfortable cabin during steady-speed cruising.
Straight-Through Performance
CORSA's straight-through muffler design increases exhaust flow by 46%, helping drivers maximize the benefits of additional performance modifications. The custom-tuned mufflers were developed specifically around the seventh-generation Mustang Coyote V8, combining increased flow with the sound characteristics CORSA engineered for the S650 platform.
4.5-Inch Black PVD Carbon Fiber Tips
This 21253CFBLK configuration features CORSA's 4.5-inch carbon fiber exhaust tips with dual-wall stainless steel inner cones finished in Black PVD. The combination of carbon fiber and the dark Black PVD inner cones provides an aggressive, premium appearance that complements the modern rear styling of the S650 Mustang GT.
Direct Fit to the Factory Mid-Pipe
The Sport Axle-Back is designed to bolt directly to the Mustang GT's factory resonated mid-pipe, making it an excellent option for owners who want to upgrade the rear exhaust section without replacing the complete Cat-Back system. For drivers looking for additional volume later, adding CORSA's Double Helixx Non-Resonated X-Pipe increases the exhaust to CORSA's Xtreme sound level.
304 Stainless Steel Construction
CORSA constructs the system from 3.0-inch 304 stainless steel for excellent durability and corrosion resistance. The Sport Axle-Back also provides approximately 8 pounds of weight savings compared to the stock exhaust.
