Borla ATAK Cat-Back Exhaust System for 2020-2025 Chevrolet Corvette C8
The Borla ATAK Cat-Back Exhaust System for the 2020-2025 Chevrolet Corvette Stingray C8 and 2024-2025 E-Ray delivers Borla’s most aggressive sound profile while maintaining a clean, drone-free driving experience inside the cabin. Engineered specifically for the mid-engine C8 platform, this premium performance exhaust system combines advanced sound tuning, premium stainless construction, and factory valve integration for an upgraded exhaust note and refined fitment.
This 3-inch inlet system includes both AFM (2020-2021) / DFM (2022-2025) valves and factory NPP dual-mode exhaust valves. Borla’s patented Polyphonic Harmonizer and SwitchFire technology work together to create a rich, aggressive, full-bodied sound while improving exhaust pulse flow and reducing turbulence. The result is a sharper, more exotic tone with performance to match.
Finished with 4-inch round black chrome tips on T-304 stainless steel, this system also includes strategic heat shielding to help protect surrounding components from exhaust heat. Built from premium T-304 stainless steel and backed by Borla’s Million Mile Warranty, this is a serious exhaust upgrade for C8 owners who want maximum attitude without sacrificing engineering quality.
