The Borla 11903CB ATAK Axle-Back Exhaust System delivers race-inspired performance and the loudest street-legal sound available for the C7 Corvette Z06 and Grand Sport. Designed for enthusiasts who demand maximum exhaust volume and aggressive tone, this system features Borla's Acoustically Tuned Applied Kinetics (ATAK) technology that shapes and focuses sound waves for optimum high-volume output without drone at cruising speeds.
