Borla Cat-Back Exhaust - Chevrolet Corvette Stingray (C8) - 3in Quad 4in Tips
This Borla cat-back exhaust suits the Chevrolet Corvette Stingray (C8) and replaces the factory system from the catalytic converter back. The 3in system includes AFM/DFM valves and NPP dual-mode exhaust valves, SwitchFire and Polyphonic Harmonizer technology, heat shielding and quad 4in round angle-cut tips (two each side). Choose S-Type (sporty) or ATAK (the most aggressive); both are tuned to avoid drone in the cabin.
Note: Includes AFM ('20-'21) / DFM ('22 on) valves and NPP dual-mode valves, so the factory active exhaust is retained. After installation, the exhaust valve controllers must be recalibrated to GM Document ID 5406413; Borla recommends having this done by a Chevrolet dealer. Borla also lists this system for 2024-2026 cars. The system ships in two boxes. Care tip: stainless steel polish is not recommended on the black chrome tips. Designed around the US left-hand-drive C8. The rear exhaust layout is shared with the factory right-hand-drive Australian Corvette, but Australian-delivered cars may carry Euro/international emissions hardware, so please confirm fitment with our team before ordering. Installation by a professional is recommended.
Features
- 3in T-304 stainless steel system with AFM/DFM and NPP valves
- Patented SwitchFire crossover that blends the combustion pulses from both banks without the turbulent centre intersection of a standard X-pipe
- Polyphonic Harmonizer technology: pipes of different diameters and lengths blend several exhaust notes into one rich, full-bodied sound
- Heat shielding included to protect the car
- Quad 4in round angle-cut tips in polished, black chrome or carbon fibre
