• ATAK Sound Level: Provides an exciting, aggressive driving experience with no interior drone
• Integrated Heat Shielding: Strategically placed throughout the system to prevent heat damage and protect your Corvette

Important Installation Note: After installation, the controllers for AFM/DFM valves and NPP valves must be recalibrated according to GM Document ID 5406413. Borla recommends visiting your nearest Chevrolet dealer for this recalibration service to ensure proper valve operation.
