Borla has developed a revolutionary new exhaust technology that enables engineers to deliver unprecedented vehicle-specific control over the acoustical note of an exhaust throughout the RPM range, while retaining 100 percent of the power-adding capabilities of Borla's patented multicore design. Called ATAK (Acoustically-Tuned Applied Kinetics), this new technology produces the highest available dB (decibel) levels in the Borla street-legal lineup, and is designed for high-performance purists who prefer exhaust notes over their stereos. The focus of ATAK is to pump the volume while retaining clarity of sound, avoiding distortion typically found in louder exhausts. With ATAK, the sound output is tuned like a graphic equalizer to shape and focus sound waves for optimum high-volume output.
