Product Description

The Borla 140957 ATAK Cat-Back Exhaust System is engineered specifically for the 2023-2026 Corvette Z06's 5.5L flat-plane-crank LT6 engine, delivering a sharper, more aggressive exhaust note without introducing cabin drone at cruising speeds. Borla's SwitchFire technology blends the pulses from both banks for a distinct tone and a modest performance gain, while the factory NPP valves remain fully functional for adjustable sound levels.

Built from T-304 stainless steel and shedding roughly 9 lbs versus the factory system, it's a direct fit using OE hangers and mounting points. Note that exhaust tips are not included and must be reused from the factory setup or purchased separately, and the NPP valve actuators require recalibration after installation - professional installation is recommended.
