  • Transforms the exhaust note of your Mustang EcoBoost to a unique aggressive performance sound

  • Weighs less than the stock system which helps your car accelerate, brake, and corner faster because lighter is always better

  • 4-inch double wall, polished T304 stainless steel tips with beveled edges add style to your ride
  • If you prefer a blackout look for the exhaust tips, choose the matte black Cerakote finish
