The Borla ATAK cat-back is the loudest, most aggressive exhaust in Borla's lineup for the C8 Corvette Z06, built around a 3 inch inlet and Borla's patented SwitchFire technology that blends combustion pulses from both banks for a distinctive tone and added performance. It retains the factory NPP dual-mode valves so the car keeps its quiet and loud modes, and strategic heat shielding protects the rear of the vehicle. Tips are not included: the system exits through the factory tips in the valance, so you reuse the OE tips or add optional Borla tips (60740CFSB). It is built from T-304 stainless steel and backed by Borla's Million Mile Warranty. Note: the NPP valve controllers require recalibration after installation per GM service documentation.
