LAS VEGAS, NV — Like many performance parts manufacturers, the exhaust experts at Borla incorporate mountains of vehicle data, advanced math algorithms, and precision measurements into their product design.

But when it comes to creating vehicle-specific exhaust systems, they must also use something less technical and largely immeasurable.




“Imagine many voices harmonizing together in a choir,” is the opening line of Borla’s news release introducing its all-new patent-pending Borla Polyphonic Exhaust Harmonizer technology which is currently available in a select number of vehicle applications with several more on the way.

The release continues, “When the right notes are sung together, an ethereal effect is created with dramatically more depth than a single voice. Pipe organs have done this for hundreds of years, using combinations of varying pipe diameters and lengths to form powerful chords.”

David Borla, the company’s vice president of sales and marketing, is an accomplished musician who was signed to a record deal by Sony, and in a moment of inspiration, launched an in-house effort with Borla’s research and development team to apply pipe organ math to automotive exhaust applications.

“We’re a sound company,” said Jason Gelinas, Borla’s marketing manager, in an interview at the 2017 SEMA Show. “We’re able to take multiple tones and mix them together to make sound. A lot of it is eliminating bad frequencies and enhancing good frequencies.”

The proliferation of small-displacement turbocharged engines has produced a bunch impressive power-to-displacement engine performance, but has mostly resulted in vehicles with uninspiring exhaust tones, relative to the hums and purrs and roars of high-horsepower V8s.

The Polyphonic Exhaust Harmonizer brings awesome exhaust sound to these types of engines, and many more, Borla officials say.

This technology will soon be available for the 2018 Ford Mustang, but Borla exhaust systems with this new music-inspired Polyphonic Exhaust Technology are currently available in the following applications:

  • 2016-2017 Ford Focus RS – Cat-Back™ Exhaust ATAK®
  • 2017 Ford Fusion Sport – Axle-Back Exhaust S-Type
  • 2016-2017 Dodge Challenger R/T – Cat-Back™ Exhaust ATAK®
  • 2016-2017 Dodge Challenger R/T – Cat-Back™ Exhaust S-Type
  • 2017 Infiniti Q60S – Cat-Back™ Exhaust S-Type
  • 2015-2018 BMW M3/M4 – Cat-Back™ Exhaust ATAK® (Coming Soon)
  • 2018 Honda Civic Type R – Cat-Back™ Exhaust ATAK® (Coming Soon)
