Give your Mustang the aggressive sound and look that it needs!


Bring your 5.0L to life with our valved axle back exhaust for your Ford Mustang! Our system will give you a beautiful sound profile no other company can duplicate. Our system is perfect for mustang owners who love their car to be loud and raspy but with minimal drone on long drives and silent cold starts early in the morning with a push of a button. This system bolts up to your aftermarket or stock exhaust.

 

 

The ValvedExhausts Catback System boasts a 3 inch pipe diameter with 4 inch tips, perfect for the 2015-2023 Mustang GT. Its vacuum actuated valves provide a lighter alternative to the OEM exhaust, while minimal drone ensures a smooth driving experience.

 

This kit contains all necessary components for installation: an axle back system, clamps, hardware, valved exhaust tips, one valved exhaust remote, one remote receiver, and all required vacuum lines.
