Borla cat-back exhaust system.

BORLA® has developed a revolutionary exhaust technology that enables our engineers to deliver unprecedented vehicle-specific control over the acoustical note of an exhaust throughout the RPM range, while retaining 100% of the power-adding capabilities of BORLA®'s patented multicore design. 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. The development of each ATAK® system begins with extensive study of each vehicle's acoustical properties. The technology is based on custom-tuned attributes of the internal muffler cores, which are calibrated on a vehicle-by-vehicle basis to deliver the most desirable sound with no drone insdie the vehicle. This system will have a very aggressive sound on Shelby GT 500 vehicles.

A cat-back system replaces everything behind the catalytic converter and leaves emissions equipment in place.
