Product Description

The Borla 140839CF is an ATAK cat-back exhaust system for the 2020-2026 Chevrolet Corvette C8 Stingray and 2024-2026 E-Ray, finished with quad 4-inch carbon fiber tips with bright centers. ATAK delivers Borla's most aggressive exhaust character -- a full-throated, high-RPM sound that eliminates in-cabin drone through SwitchFire® and Polyphonic Harmonizer technology. SwitchFire's patented design blends combustion pulses from both cylinder banks for improved performance and a custom aggressive sound. Polyphonic Harmonizer utilizes pipes of varying diameter and length to layer multiple exhaust notes into a rich, full-bodied tone.

This system includes both AFM/DFM valves and OEM NPP dual-mode valve assemblies -- it requires an NPP-equipped car and will not fit non-NPP Corvettes. After installation, valve actuator recalibration is required per GM Document ID 5406413; Borla recommends having this performed at a Chevrolet dealer. Strategically placed heat shielding protects the C8's composite bodywork. Chrome tip version available as Borla 140839. Ships in 2 boxes. Made in the USA and backed by Borla's Million-Mile Warranty.
