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!

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.

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