Another day, another Stage 3 NA! 🔥
This 18+ Mustang GT came to us for X-Force long-tube headers and a custom ECU calibration, building on its existing cold-air intake.
Final results: 445 WHP & 388 ft-lbs at the wheels.
Our Stage 3 NA builds are incredibly popular, and for good reason. More performance, improved efficiency, and a far more engaging driving experience, all while retaining the naturally aspirated V8 character we love.
The result? A Mustang that delivers the kind of response, sound, and driving feel you’d expect from a 500+ bhp V8.
