Borla ATAK Cat-Back Exhaust for the C8 Corvette Stingray with NPP (Polished Tips)
The Borla ATAK 140839 cat-back is built for 2020–2026 C8 Corvette Stingray owners who want a more aggressive exhaust personality while keeping the factory NPP valved performance exhaust functionality. With 3-inch main piping and polished stainless tips, it’s a fitment-first upgrade that adds sound presence without changing the car’s valve-equipped layout.
