Frequently Asked Questions
What is the CORSA 14762BLK?The CORSA 14762BLK is a 2.75-inch Xtreme valve-back exhaust for the 2014-2019 C7 Corvette Stingray and Grand Sport with automatic transmission and factory NPP valve, featuring twin 4.5-inch quad matte black PVD tips and CORSA RSC technology at its loudest, most aggressive tuning level.
Does the 14762BLK work with the factory NPP active valve?Yes. The CORSA 14762BLK installs downstream of the factory NPP valve, preserving quiet and sport driver modes while delivering CORSA Xtreme sound when the valve is open.
How does the 14762BLK differ from the 14762?Both are valve-back systems for the same C7 platform with NPP. The 14762 is Sport-level tuning with polished tips; the 14762BLK is Xtreme-level tuning with matte black PVD tips and a substantially louder, more aggressive sound.
Is this compatible with the C7 Z06 or ZR1?The CORSA 14762BLK is designed for the C7 Stingray and Grand Sport. Z06 and ZR1 use different exhaust routing and require their own specific CORSA fitments.
Is the 14762BLK drone-free at highway speeds?RSC technology manages resonance at the Xtreme level. Highway cabin volume will be higher than Sport tuning but without the harshest drone peaks.
Does this fit manual transmission C7 Corvettes?The CORSA 14762BLK is designed for automatic transmission C7 models with the factory NPP valve. Manual transmission owners should verify fitment with CORSA before ordering.
Is a tune required after installation?No. The CORSA 14762BLK is a bolt-on valve-back replacement with no ECU tune, cutting, or welding required.
What warranty does the 14762BLK carry?CORSA provides a limited lifetime warranty against defects in materials and workmanship when purchased from an authorized dealer.
