Borla ATAK Cat-Back Systems
Mount an offensive to regain optimum acoustics with Borla ATAK cat-back systems. Your modern muscle car will not only be performance-enhanced, but also acoustically tuned to a loud, aggressive exhaust note. ATAK (acoustically tuned applied kinetics) technology produces the highest dB levels, avoiding distortion to retain clarity.
Tuned like a graphic equalizer, these cat-back systems are custom-tuned for your specific vehicle, delivering the most desirable sound to your ears. Plus, you retain all of the power-adding capabilities of Borla's multi-core design. The exhausts are handmade by master craftsmen from premium 300-Series austenitic stainless steel and ultra-smooth, mandrel-bent piping.
