The CORSA 14766BLK is the matte black tip variant of the Xtreme-level axle-back exhaust built for the 2015-2019 Chevrolet Corvette C7 Z06, Grand Sport, and ZR1 with manual transmissions without the factory NPP active exhaust valve. It delivers the same RSC-tuned maximum aggressive sound as the polished 14766 but exits through twin 4.5-inch matte black PVD Pro-Series tips that complement the Z06's aggressive exterior. Built from 2.75-inch mandrel-bent T304 stainless steel throughout, the 14766BLK is CORSA's loudest axle-back option for these high-performance C7 variants.

Frequently Asked Questions
Will this CORSA product fit my 2015-2018 Chevrolet Corvette?
That vehicle range is listed, but confirm the exact manufacturer part number, trim, cab or body style, factory exhaust or intake configuration, and every application note before ordering.
How should I choose the correct CORSA exhaust configuration?
Compare sound level, pipe diameter, exit location, tip finish, factory valve or active-exhaust requirements, cab and bed or body configuration, and the exact part number.
Does this CORSA exhaust require professional installation?
Vehicle-specific systems are generally bolt-on when the exact application matches. Universal components can require cutting and welding. Professional installation helps ensure alignment, clearance, sealing, and correct clamp torque.
Installation Instructions
Follow CORSA and vehicle service instructions. Allow the exhaust to cool, support the vehicle safely, confirm the factory connection and hangers, align the tips before final tightening, check for leaks, and recheck clamp torque after the first heat cycle.
