“what’s the best exhaust system to upgrade to for a deeper sound on my 2014 Mustang GT?”
For the deepest exhaust sound on your 2014 Mustang GT, here are the top 3 recommendations:
Borla S-Type Cat-Back (Part #140515) - $1,600-1,900
Flowmaster Super 44 (Part #942548) - $400-600
Corsa Sport (Part #14321) - $1,400-1,700
Key Tips for Maximum Depth:
The Flowmaster 40 series mentioned in your search will give you that classic deep muscle car sound, but expect significant drone at highway speeds. The Super 44 improves on this with less drone while maintaining the deep tone.
