Borla 140839BC ATAK Cat-Back Exhaust System C8 Corvette 6.2L V8 Black Chrome Tips

The Borla 140839BC ATAK Cat-Back Exhaust System delivers an aggressive, race-inspired sound for the 2020-2025 C8 Corvette, including the E-Ray model. Engineered specifically for the mid-engine C8 platform, this premium exhaust system features a 3-inch inlet design and incorporates both AFM/DFM valves (Active Fuel Management/Dynamic Fuel Management) and NPP (National Performance Package) dual mode exhaust valves for complete integration with factory systems.

Advanced Sound Technology:

This system showcases Borla's signature ATAK (Acoustically-Tuned Applied Kinetics) sound level—the most aggressive tone in the Borla lineup—while eliminating interior drone. The exhaust features Borla's Polyphonic Harmonizer Technology, which utilizes patented units containing pipes of different diameters and lengths to create multiple exhaust notes that harmonize for a clean, rich, full-bodied sound. The patented SwitchFire technology completely eliminates the turbulent center intersection of standard X-pipes, truly blending combustion pulses from both sides of the engine for improved performance and a custom aggressive exhaust note.

Premium Construction and Protection:

• Constructed from premium T-304 stainless steel for maximum durability and corrosion resistance
• Features four 4-inch round black chrome tips on T-304 stainless steel
• Includes strategically placed heat shielding to prevent exhaust heat damage
• Backed by Borla's Million Mile Warranty
• Complete cat-back system with all necessary hardware included

Important Installation Notes:

After installation, the controllers for the AFM/DFM valves and NPP valves must be recalibrated according to GM Document ID 5406413. Borla recommends having this recalibration service performed at a Chevrolet dealer. For cleaning the black chrome tips, use hot water and a microfiber cloth only—do not use Borla Stainless Steel Polish (P/N 21461) on black chrome finishes. This system ships in two boxes. Also available with bright chrome or carbon fiber tip options.
