Borla® Exhaust Systems with Polyphonic Exhaust Technology

Imagine many voices harmonizing together in a choir. 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. This technology caught the attention of our VP of Sales & Marketing David Borla, whose many years composing and performing in the music industry included a record contract with Sony. David worked with our R&D team to apply organ pipe mathematics to exhaust applications. The exciting result is the Borla Polyphonic Exhaust Harmonizer, which is now featured in select Borla exhaust systems.

ATAK® Technology

BORLA® ATAK® (Acoustically Tuned Applied Kinetics) technology is designed for high-performance purists who prefer exhaust sound over their stereos. ATAK®-equipped exhaust systems deliver the highest available dB (decibel) levels in the BORLA® street-legal lineup... and unlike inferior brands that lose significant sound quality at higher volumes, ATAK® is tuned like a graphic equalizer to shape and focus sound waves for optimum high-volume output.

ATAK® technology is based on specifically-tuned attributes of the internal muffler cores, which are calibrated on a vehicle-by-vehicle basis to deliver the most desirable sound. For more details and to hear the difference, watch our ATAK® videos below for different make and model vehicles.

The power of BORLA® Multicore® technology, with the sound of vehicle-specific acoustic tuning! These patent-pending units contain pipes of different diameters and lengths to create multiple exhaust notes that harmonize to deliver a clean, rich, full-bodied sound to the Borla mufflers. The mufflers then enhance this sound to the character and volume appropriate for our Touring, S-Type and ATAK® systems. The limitless combination of pipe diameters and lengths allows Borla to tune each application so that the best notes and harmonics of specific engines are highlighted. Thanks to the straight-through design of the Harmonizers, Borla customers get the ultimate in tuned exhaust sound with zero loss in performance.

Borla Exhaust System

Upgrading your factory exhaust system to a Borla stainless steel performance exhaust system with a more efficient and less restrictive design can improve sound (adding more enjoyment driving your vehicle) and increase engine horsepower and torque throughout the RPM range (allowing quicker acceleration to pass a vehicle or get to highway speeds quicker). Borla offers Axle Back exhaust systems, Cat back exhaust systems, and for select Competition-Use-Only vehicles, we offer long tube headers to replace your exhaust manifold for the best performance and sound.

Borla Cat Back System

The Borla "Cat Back™" name implies the exhaust system is located behind the factory catalytic converter where there factory emissions remain untouched and vehicle stays emissions compliant. This remains distinct from the Axle Back exhaust system that is located behind the rear axle. Alex Borla coined the phrase 'Cat Back' and introduced the Cat Back performance exhaust in 1978, a bolt-on replacement performance exhaust system requiring no welding, thus being secured using the factory hanger locations.

Borla Cat Back exhaust systems use engine-specific (not universal) mufflers that are designed, tested, and optimized specifically for a particular year/make/model vehicle. Borla Cat Back systems increase the overall sound level & performance. Vehicles that don't have a factory service-point require "cutting" the factory exhaust system before installing a Borla Cat Back performance exhaust system. Borla includes instructions where to make this cut and includes the hardware to complete the installation.

Many of today's modern vehicles have a factory service-point in the exhaust system (flange or slip-fit) located in the exhaust tubing behind the catalytic converter. A Borla Cat Back performance exhaust system replaces the factory exhaust system (behind this service-point) following the same exhaust path and secured using the original vehicle hangars and rubber isolators.

Borla pioneered the automotive exhaust aftermarket in exhausts constructed in aircraft grade 304 stainless steel tubing, a material with higher content of carbon & nickel that won't rust or corrode.

Borla Axel Back System

A Borla "Axle Back" or rear section exhaust implies the exhaust system is located behind the vehicle rear axle . Most installations are completed in less than an hour and require no cutting of the factory system. A Borla Axle Back performance exhaust is a less restrictive aftermarket exhaust system that will improve the sound level both inside the cabin and exterior. Borla Axle Back exhaust systems use engine-specific (not universal) mufflers that are designed, tested, and optimized specifically for a particular year/make/model vehicle.

Improvements in sound and performance are accomplished by using a superior straight-through muffler design, mandrel-bent tubing, and the application of proper engine-matched tubing diameter. In some vehicles Borla offers multiple sound levels (Touring, S-Type, and ATAK®) to suite the individual driver's taste in vehicle sound. Borla also offers the Cat Back exhaust system which is located behind the factory catalytic converter.

Borla Axle Back systems replace the factory rear mufflers and exhaust pipe with an improvement in overall sound & performance to your truck, SUV, or car. Welded tips are standard on most systems running gas or diesel fuels.

Some of today's modern vehicles have a factory service-point in the exhaust system (flange or slip-fit) located in the exhaust tubing behind the vehicle rear axle. A Borla Axle Back performance exhaust system replaces the factory exhaust system (behind this service-point) following the same exhaust path and secured using the original vehicle hangers and rubber isolators.

Vehicles that don't have a factory service-point require “cutting" the factory exhaust system before installing a Borla Axle Back performance exhaust system. Borla includes cutting instructions and hardware to complete the installation.
