Borla ATAK Axle-Back Exhaust for C7 Corvette Z06 with NPP (11905)

Borla ATAK 11905 is an axle-back upgrade for the 2015–2019 C7 Corvette Z06 that keeps the factory-style NPP dual-mode valve setup while delivering a sharper, more aggressive sound character. If you want a bigger change than stock without replacing the full system, this is a clean “rear section” swap that also finishes the car with a quad center-exit look.
