The Borla 140839BC ATAK cat-back is built for C8 Corvette Stingray owners who want Borla’s most aggressive sound profile while retaining the factory NPP valve functionality. This system uses 3-inch main piping and finishes with black chrome rear tips for a darker, high-contrast look at the rear fascia.

Why Borla Leads
- Long-standing U.S. exhaust manufacturer with platform-specific Corvette development
- T-304 stainless construction focused on corrosion resistance and long service life
- Consistent system fitment and repeatable sound outcomes by design (not “universal” tuning)

What to Expect After Installation
You should expect a more aggressive exhaust note than stock, with the ability to retain factory mode/valve behavior through the NPP actuators. If a check-engine light occurs after installing a valved cat-back, a valve relearn procedure may be required depending on vehicle tolerance stack and valve calibration.

- This fits the 2020–2025 Chevrolet Corvette C8 Stingray (LT2 6.2L) exactly.
- Coupe and Convertible models
- RWD automatic transmission application.
