Borla S-Type Cat-Back Exhaust for C8 Corvette Stingray with NPP (140838)
Borla engineered the S-Type 140838 for C8 Stingray owners running factory NPP (dual-mode) who want a deep, balanced tone that feels stronger than stock without turning the cabin into a constant roar. This system pairs SwitchFire® and the Polyphonic Harmonizer to shape a cleaner, richer sound character while keeping the street-build vibe intact.
