Borla atak exhaust system



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!

BORLA® R&D has worked hard to bring two different sound levels for the F80 M3 and the F82 M4. For those looking for a more tame system with a deeper tone, we recommend our S-Type Cat-Back™. For the owner who is looking for an aggressive and head-turning sound, we recommend our ATAK® system. Both systems will provide improved sound, performance, and of course, a drone-free experience. You can rest assured that Borla will help bring out the sweet sounds of the S55 engine.
