“what’s the best exhaust system to upgrade to for a deeper sound on my 2014 Mustang GT?”

Rusty assistant avatar

For the deepest exhaust sound on your 2014 Mustang GT, here are the top 3 recommendations:

  1. Borla S-Type Cat-Back (Part #140515) - $1,600-1,900

    • Best overall balance of deep tone and minimal drone
    • Straight-through design with patented anti-drone technology
    • Deep, aggressive V8 rumble without excessive cabin noise
    • Premium T-304 stainless steel construction
  2. Flowmaster Super 44 (Part #942548) - $400-600

    • Deeper tone than the original 40 series with less drone
    • Classic muscle car sound with Delta Flow technology
    • More budget-friendly option
    • Slightly louder than Borla but manageable daily
  3. Corsa Sport (Part #14321) - $1,400-1,700

    • Zero drone technology with deep tone
    • More refined sound profile
    • Higher price but excellent build quality

Key Tips for Maximum Depth:

  • Pair with an H-pipe instead of X-pipe for deeper tone
  • Consider keeping factory resonators if you want deeper but not overly loud
  • The Borla S-Type offers the best compromise between depth and livability

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.
