Borla ATAK Axle-Back Exhaust System (11869CB) - 2014-2019 Chevrolet Corvette C7 Stingray 6.2L V8 (Valve-Delete / Without NPP)
Unleash the loudest, most aggressive, completely unrestricted race-inspired soundtrack available for your sports car with the Borla ATAK Axle-Back Exhaust System. Custom-engineered specifically for 2014 to 2019 Chevrolet Corvette C7 Stingray models, this premium aftermarket upgrade is designed for enthusiasts who want a complete mechanical valve-delete solution. By completely removing both Active Fuel Management (AFM) and factory dual-mode performance exhaust (NPP) valves, this free-flowing system provides maximum exhaust pathway optimization. ATAK (Acoustically-Tuned Applied Kinetics) technology relies on vehicle-specific internal muffler cores that are precisely calibrated to focus sound waves into a high-definition, earth-shaking V8 growl under heavy throttle. While the exterior volume remains fiercely intense, Borla's painstaking engineering ensures the interior cabin remains devoid of harsh resonance or drone during highway cruising. Constructed with a high-flow 2.75-inch pipe diameter that transitions to dual 2-inch outlets, this layout maximizes exhaust gas velocity and optimizes scavenging to unlock hidden horsepower and sharpen throttle response.
What sets the Borla 11869CB apart is its valve-free architecture. It does NOT contain functioning AFM or NPP internal exhaust valves; instead, it features non-functioning physical bracket mounts where your factory electronic AFM actuators can be securely bolted to keep them away from moving parts beneath the chassis. Fabricated entirely from premium, aircraft-grade T-304 austenitic stainless steel, this setup is vastly superior to budget aftermarket alternatives or factory T-400 series alloys (such as 409) to provide permanent protection against deep rust, moisture corrosion, and structural cracking. Precision computer numerical control (CNC) manufacturing and ultra-smooth mandrel bends ensure a direct, line-to-line bolt-on slip fitment. The center-exit rear section is finished with a stunning set of quad 4.25-inch round, rolled angle-cut intercooled ceramic black coated T-304 stainless steel tips for an aggressive, custom stealth look. For a complete exhaust overhaul, this axle-back can be paired with Borla's optional mid-section X-Pipe (Part #60548) to create a full Cat-Back system.

Important Application & Valve Notes:
- Fits **2014-2019 C7 Corvette Stingray base models only**. Does NOT fit Grand Sport, Z06, or ZR1 configurations.
- Fits **6.2L LT1 V8 engines only**. Does not fit supercharged LT4 or LT5 platforms.
- **Check Engine Light Warning:** Because this system does not contain internal AFM valves to change backpressure during cylinder deactivation, **a Check Engine Light (CEL) will occur** on vehicles equipped with factory AFM unless electronic valve simulators are used or the AFM system is tuned/disabled in the vehicle computer.
- Intended strictly for vehicles that are either NOT equipped with factory NPP dual-mode exhaust, or for owners looking to completely disable and delete both the AFM and NPP valve functions.
