PRODUCT DETAILS ▾
The CORSA Sport axle-back exhaust (part 21253) fits the 2024+ Ford Mustang GT S650 Fastback (coupe) with the 5.0L Coyote V8 and the non-active (non-valved) factory exhaust. It replaces only the rear mufflers and bolts to the factory resonated mid-pipe. CORSA rates the Sport level at about 7-8 dB louder than stock, with No DRONE RSC technology for a quiet cabin at cruise.

FAQ
Will it fit a Mustang GT with the active valve exhaust?
No. Part 21253 is built for the non-active (non-valved) GT. CORSA sells separate valved systems for cars with Active Valve exhaust.
What is the difference between an axle-back and a cat-back?
The axle-back replaces only the rear mufflers and tips and keeps the factory resonated mid-pipe. A cat-back also replaces the pipework back to the catalytic converters.
