Borla Set to Introduce Drone-Free ‘Polyphonic’ Technology at SEMA

2014 Chevrolet Corvette Stingray

Using science, Borla wants to change how you hear your car.

By using music theory and repurposing vintage pipe organ technology, Borla is changing the way they make exhausts with polyphonic advancements. They claim that this new way of making an exhaust allows a richly textured sound, while maximizing performance by promoting exhaust gas flow.

This system looks and sounds different than anything currently on the market, and allegedly produces more power throughout the full powerband.

David Borla, VP of sales and marketing for the company, studied pipe organs to determine how formulas for pipe length and diameter are used to create different notes. Using his background in music he was able to choose specific notes to combine together for a more pleasing and drone-reducing exhaust note.

They say it will be a “game changer” in the industry, and they’re confident that their customers will be quite happy with the experience. He went on to say, “By using timbre scaled variations in pipe diameter, length and shape, Borla continues to raise the bar in performance exhaust technology.”

This polyphonic technology will be incorporated into Borla’s current product line, including fitments for a variety of Corvette models. As usual, Borla remains committed to designing their products in California and manufacturing in their Tennessee facility from T-304 aerospace-grade stainless steel. This product will also carry the company’s signature million mile warranty. While we haven’t heard this technology in practice quite yet, we’ll be sure to check it out when we’re on the floor at SEMA to bring you more.

As a side note, Corvette Forum’s sister site, Rennlist, will be getting a polyphonic exhaust on its #ProjectStork Porsche 911 S project car. We’re excited to see how this system beautifies an already sonorous flat-six.
