Ford has announced the arrival of a new performance pack for the Mustang EcoBoost, and it comes in the form of a new, fully active performance exhaust that is said to “excite the senses and deliver a note of performance.”

The Blue Oval’s “audio designers” have designed specific acoustic exhaust sounds for the 310 hp pony car, one that is powered by a 2.3 litre turbocharged four-cylinder engine. In stock form, the four potter is nowhere near the 5.0 litre Coyote V8’s deep, raspy exhaust sound, but Ford says all that will change once the exhaust system becomes available.

“We’re probably the few engineers here who do not have to design to a number or a specification,” said Ford exhaust development engineer Hani Ayesh. “Instead, we work to identify that signature sound DNA that connects drivers to the emotional expectation they have for a specific car.”

The sound engineers rely on computational analysis to design, for example, a computer-controlled active exhaust system that opens valves – much like a saxophone or a large pipe organ – to change the sound of the car based on the mood of the driver.

According to the company, stepping the gas on a Mustang EcoBoost fitted with the exhaust delivers a throaty rumble that makes the hair on the back of your neck stand up, just as it might on the larger-engine Mustang GT and Shelby GT350 models.

There’s a switch on the centre console to toggle between quiet, normal and sport/track settings, and each mode intensifies the exhaust sound. “When I pick up my kids from school, they want to hear that growling rev of the engine,” said Ayesh, “but my wife and neighbours, not so much. So I can select the quieter ‘good neighbour’ mode, and keep them happy, too.”

Back home, the Mustang is offered in two flavours, starting with the entry-level 2.3L EcoBoost (RM489k) and Mustang GT (RM599k). For a more detailed look at their respective equipment and specifications, check out Also, click here to read our in-depth review of the pony car.
