Borla takes an old concept and adapts it in a new way that may change the exhaust game completely.What do you prefer when you"re looking for a new exhaust system? If you want lots of noise, break out the Sawzall or weld some glasspacks in. When you"re building something a little nicer you want it to sound good too. If you’re like us, you start watching YouTube videos to see what sounds best. David Borla, VP of Sales and Marketing at Borla, began working on combining music theory with vehicle exhausts and made a breakthrough with polyphonic technology. That means "many sounds, simultaneously" and is better known as the technical name for what a pipe organ is doing.David matched pipe length and diameter to create different notes that work together in natural harmony. What does this have to do with your V8? This ability lets Borla create an exhaust that brings out specific frequencies, and notes, in a given engine"s sound signature. Beyond that, it allows them to highlight different frequencies, allowing them to create multiple different exhausts for a given vehicle or engine. Looking to bring out the rumble? Maybe something in the mid range? Borla claims they can do this all without sacrificing performance or creating the dreaded drone."The instrument uses variations in pipe diameter and length to make different notes. This concept lends itself perfectly to exhaust design because it will allow us to alter exhaust notes without restricting gas flow," explains Borla. "We"ve actually taken historical pipe organ ratios, calculations, and formulae to combine pipes so we can create, manipulate and control polyphonic pitch harmony in an exhaust system without restricting performance."We"ll wait to hear the results before declaring a verdict, but color us intrigued. We"ll have people at the 2017 SEMA show in Las Vegas this week, so keep an eye, and an ear, out for an update on this promising new technology.Tags: 2017 SEMA, Borla, Exhaust System, Polyphonic, SEMA
