Hear the Difference

    • Transforms the exhaust note of your Mustang EcoBoost to a unique aggressive performance sound
    • Loud but not harsh
    • Muffler delete means maximum volume from idle throughout the RPM range
    • If a full time, tough performance sound is your desire, this is the system for you

      Feel the Performance

        • Muffler delete and mandrel tube bending provides for maximum exhaust gas flow and maximum back pressure reduction increasing horsepower
        • 2.5-inch diameter exhaust tubing reduces exhaust gas flow restrictions producing noticeable performance gains Improved exhaust gas flow supports and complements future performance modifications
        • Weighs less than the stock system which helps your car accelerate, brake, and corner faster because lighter is always better
        • Larger diameter exhaust tubing and lighter weight reduces mass and improves gas mileage fuel economy

          Get Noticed

          • 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 Great sound boldly announces your presence and great looks turn heads and get positive comments!
