Description
Refine and enhance the sound of your 2024 Mustang GT Convertible with the CORSA 3.0" Axle-Back Exhaust System featuring 4.5" Polished Pro-Series Slash Cut Tips. Designed specifically for the 7th Generation S650 Mustang GT 5.0L Coyote V8 without Active Valve Exhaust, this axle-back system delivers improved exhaust tone, reduced weight, and drone-free performance.
Constructed from premium 304 stainless steel, the system features straight-through custom-tuned mufflers engineered exclusively for the latest Coyote V8 platform. The Sport version bolts directly to the factory resonated mid-pipe and produces a moderately aggressive tone during cold starts and acceleration while maintaining a comfortable cabin experience at cruising speeds thanks to CORSA’s patented No DRONE RSC® technology.
With a straight-through muffler design, this axle-back system increases exhaust flow by up to 46%, helping drivers maximize the performance benefits of both stock and modified setups. The system is finished with quad 4.5" dual-wall polished Pro-Series slash cut stainless steel tips, giving the Mustang GT Convertible a sharper, more aggressive rear appearance.
Available in two refined sound profiles:
Sport Sound Level – Part Number 21272
-
9 lbs weight savings
-
+7–8 dB louder than stock
-
Noticeably deeper and more aggressive tone
Touring Sound Level – Part Number 21276

For those seeking maximum aggression, pairing this axle-back with CORSA’s Double Helixx Non-Resonated X-Pipe increases sound output to Xtreme sound levels.
